Understanding Siding Nailer Nails: The Foundation of a Great Job
When you’re working with a siding nailer, the type of nail you use is just as important as the nailer itself. It’s not just about driving a nail; it’s about driving the right nail, in the right way, for the right material. Think of it like using the right key for a lock – it has to be the correct shape and size to work smoothly and effectively. This makes all the difference between a secure, long-lasting siding installation and one that might lead to headaches down the road.
Siding nailers are specialized tools designed for the unique demands of installing exterior cladding. They need fasteners that can pierce tough materials, hold them firmly against the elements, and blend in seamlessly. Using the wrong nails can lead to a frustrating experience – imagine your nailer jamming repeatedly, or worse, the nails not holding the siding securely, leading to unsightly gaps or even damage. This guide will break down all the essential factors to consider, ensuring you choose siding nailer compatible nails that make your project a success.
Key Features of Siding Nailer Nails
Siding nails aren’t your everyday carpentry nails. They’re engineered with specific characteristics to perform optimally in the demanding world of exterior cladding. Understanding these features will empower you to make the best choice:
- Diameter (Gauge): This refers to the thickness of the nail. Thicker nails offer more holding power, which is crucial for siding that needs to withstand wind and weather. For most vinyl and fiber cement siding, you’ll typically be looking for nails in the 0.113″ to 0.131″ range.
- Length: The length of the nail determines how deep it penetrates into the framing. For most siding applications, nails should penetrate the studs by at least 1.5 inches. This ensures a solid grip. Typical lengths range from 1 1/2 inches to 2 1/2 inches, depending on the siding thickness and manufacturer recommendations.
- Head Type: The head of the nail is critical for holding power and appearance. For siding, you’ll commonly find:
- Full Round Head: These offer the best holding power because their larger surface area grips the siding material. They are commonly used for wood siding and other applications where maximum strength is required.
- Flat Head / Modified Round Head: These are often used with vinyl siding or where the nail head needs to sit flush or slightly below the surface without tearing the material.
- Collation Type: This is how the nails are held together in strips for your nailer. The two main types are:
- Plastic Collated: Nails are held together with plastic strips. These are generally more durable and less likely to break in wet conditions compared to paper collated fasteners. They also tend to create less debris.
- Paper Collated: Nails are held by paper strips. These are common and can be slightly less expensive. However, they can be more prone to breaking apart when wet.
- Sheathing: This is a thin coating applied to nails to help them drive more easily into wood and prevent rust. Common coatings include vinyl, epoxy, or hot-dip galvanization. For exterior use, it’s essential to use nails with appropriate corrosion resistance.
- Material: The metal the nail is made from is vital for durability and corrosion resistance. Stainless steel is the most corrosion-resistant but also the most expensive. Hot-dip galvanized nails offer good protection for most exterior applications.
Types of Siding Nailers and Their Nail Requirements
Not all siding nailers are created equal, and their design dictates the specific type of nails they require. Understanding your nailer is the first step to choosing compatible nails. Let’s break down the common types:
1. Pneumatic Siding Nailers
These are the workhorses of the siding world, powered by an air compressor. They’re known for their power, speed, and reliability. Because they are designed for heavy-duty use, they require robust fasteners.
- Nail Type: Pneumatic siding nailers typically use either plastic-collated or paper-collated nails. The angle of the collation strip (e.g., 15-degree or 21-degree) is crucial and must match your specific nailer model.
- Nail Size: They generally accommodate a range of lengths and diameters suitable for various siding materials, from wood shakes to fiber cement. Always check your nailer’s manual for the recommended gauge (diameter) and length. For instance, many pneumatic siding nailers can handle 0.120” to 0.131” diameter nails and lengths from 1.5” to 2.5”.
- Head Style: They are designed to drive nails with full round heads for maximum holding power, especially important for structural integrity and resisting wind uplift on heavier siding materials.

2. Cordless/Battery-Powered Siding Nailers
These offer incredible convenience and portability, eliminating the need for an air compressor and hose. They use either a battery-powered motor driving a mechanism or sometimes a small fuel cell in conjunction with the battery.
- Nail Type: Similar to pneumatic nailers, cordless models use either plastic-collated or paper-collated nails. Again, the collation angle is critical. Some newer models might have specific proprietary fastener requirements, so checking your manual is a must.
- Nail Size: These nailers are often designed for specific size ranges, typically accommodating nails between 1 1/4” and 2” in length and often in the 0.080” to 0.113” diameter range, depending on the nailer’s power. They might be less suited for the largest, heaviest siding materials compared to high-powered pneumatic models.
- Head Style: Often designed for ease of use and compatibility with common siding materials, they can accommodate both clipped-head and full round-head nails, but it’s vital to match the specific nail required by your model.
3. Coil Siding Nailers
Coil nailers are known for their high capacity, holding hundreds of nails in a spool-like “coil.” This means fewer reloads and increased efficiency on large jobs.
- Nail Type: Coil siding nailers typically use wire-collated nails. The wires holding the nails together can be either smooth, ring shank, or screw shank. This collation is distinct from plastic or paper.
- Nail Size: They are available in various lengths, usually from 1” to 2.5”, to suit different siding thicknesses. The wire collation means you get a continuous feed without interrupted strips.
- Head Style: Coil siding nailers often drive nails with a slightly smaller head than a traditional round head, often referred to as a “full round head” but visually different from what you might see in a framing nailer. This is to prevent over-driving through softer siding materials while still providing good holding power.
Choosing the Right Nails: A Step-by-Step Approach
Selecting the correct nails might seem daunting at first, but by following these steps, you’ll be well-equipped to make the right choice for your project. This systematic approach ensures you don’t overlook any critical details.
Step 1: Consult Your Siding Manufacturer’s Recommendations
This is the most important step! Your siding manufacturer knows their product best and will specify the type, size, and material of fasteners required for optimal performance and to maintain any warranties. Always refer to the installation manual that came with your siding. It will typically detail:
- Recommended nail length (e.g., 1-3/4″ for 3/4″ lap siding).
- Recommended nail diameter (gauge) (e.g., 0.113″ to 0.120″).
- Required head diameter and style.
- Required corrosion resistance (e.g., hot-dip galvanized, stainless steel).
- Nail collation type and angle.
Ignoring these guidelines is one of the quickest ways to void your siding’s warranty or end up with a poorly performing installation.
Step 2: Check Your Siding Nailer’s Manual
Once you know what the siding manufacturer recommends, cross-reference it with your nailer’s specifications. Your siding nailer manual will tell you:
- The range of nail lengths and diameters it can safely drive.
- The required collation type and angle (e.g., 15-degree plastic collated, 21-degree paper collated, wire coil).
- Any limitations on head style or nail diameter.
The goal is to find a nail that meets both sets of requirements, with your siding manufacturer’s specs taking top priority. For example, if the siding requires 1-3/4″ nails, but your nailer can only drive up to 1-1/2″, you’ll need to either find a nailer that can accommodate the correct length or use a different fastening method.
Step 3: Consider the Siding Material
The material of your siding significantly influences your nail choice:
- Vinyl Siding: Typically requires nails that are long enough to go through the vinyl and into the sheathing/studs, but not so long that they protrude or restrict the vinyl’s natural expansion and contraction. Nails should not be driven in too tight; they should allow the vinyl to “float.” The Vinyl Siding Institute provides comprehensive installation guidelines, emphasizing proper fastening.
- Recommended Nail Size Example: 1-1/2″ to 1-3/4″ length, 0.113″ diameter with a small head that won’t tear the vinyl.
- Corrosion Resistance: Hot-dip galvanized or stainless steel.
- Fiber Cement Siding: This material is durable but can be brittle. It requires nails that provide strong holding power to prevent shifting and rattling.
- Recommended Nail Size Example: 1-1/2″ to 2″ length, 0.113″ to 0.131″ diameter with a full round head.
- Corrosion Resistance: Hot-dip galvanized (minimum G185 coating) or stainless steel is essential due to the density of fiber cement.
- Wood Siding (including Shingles and Shakes): Requires nails that offer excellent holding power and can penetrate deep into the wood framing. The aesthetic is also important, so selecting a nail that complements the wood is key.
- Recommended Nail Size Example: 2″ to 2-1/2″ length, 0.131″ diameter with a full round head for maximum grip.
- Corrosion Resistance: Hot-dip galvanized (G185) or stainless steel is non-negotiable for exterior wood applications to prevent staining and rust streaks. For untreated wood, aluminum or stainless steel might be preferred.
- Engineered Wood Siding: Similar to fiber cement or wood, it requires robust fastening. Always follow the specific manufacturer’s guidelines for engineered wood siding.
- Recommended Nail Size Example: Varies by product, but typically 1-1/2″ to 2″ length, 0.113″ to 0.131″ diameter with a full round head.
- Corrosion Resistance: Hot-dip galvanized or stainless steel.
Step 4: Determine the Correct Corrosion Resistance
Exterior applications demand fasteners that can stand up to moisture, humidity, and temperature fluctuations without corroding. Rusting nails not only look terrible but can compromise the structural integrity of your siding.
- Hot-Dip Galvanized: This is the most common and cost-effective option for exterior use. Nails are dipped in molten zinc, creating a thick, durable coating. Look for a designation like G185 (meaning 1.85 ounces of zinc per square foot of steel wire), which offers excellent protection for most environments.
- Stainless Steel: Offers the highest level of corrosion resistance and is ideal for coastal areas, high-humidity environments, or when working with specific types of wood (like cedar or redwood) that can react with galvanized coatings. While more expensive, it’s the best choice for longevity.
- Coated Nails (Vinyl, Epoxy): Some nails have specialized coatings designed for specific applications. These can be effective but ensure they meet the requirements for exterior use and are compatible with your siding and nailer.
For any siding project exposed to the elements, avoid plain steel nails or electro-galvanized nails, as they offer minimal corrosion protection and will likely rust quickly.
Step 5: Match Collation Type and Angle
This is where your nailer’s specific design really comes into play. The collation type (plastic, paper, wire) and the angle at which the nails are joined are critical. Using the wrong collation type can cause jams, damage the nailer, or be impossible to load.
- Plastic Collated: Usually at a 15-degree or 21-degree angle. They are durable and create minimal debris.
- Paper Collated: Also commonly at 15-degree or 21-degree angles. Can be slightly less expensive but may break apart more easily, especially in damp conditions.
- Wire Collated: Used in coil nailers. Nails are joined by wires, offering high capacity.
Crucial Tip: Always match the collation angle of the nails precisely to what your siding nailer is designed for. Look for markings on your nailer or in its manual (e.g., “15° Plastic Collated”). If you try to load 21-degree nails into a 15-degree nailer, they simply won’t feed correctly.
Common Siding Nailer Nail Mistakes to Avoid
Even with the best intentions, it’s easy to make a misstep when choosing nails. Here are some common pitfalls and how to sidestep them:
- Using the Wrong Length: Nails that are too short won’t provide adequate holding power, while nails that are too long can go through the sheathing and into voids, or worse, protrude through the other side of the wall framing, creating hazards. Always adhere to manufacturer recommendations for penetration depth.
- Incorrect Diameter (Gauge): Nails that are too thin may bend or fail to hold the siding securely, especially under wind load. Nails that are too thick might split the siding material or be difficult for the nailer to drive.
- Insufficient Corrosion Resistance: Using anything less than hot-dip galvanized (G185) or stainless steel for exterior siding is asking for trouble. Rusting nails can stain your beautiful new siding and weaken the attachment.
- Mismatched Collation: Attempting to force the wrong collation type (e.g., paper into a plastic-only feeder) or angle will lead to constant jams and frustration.
- Over-Driving or Under-Driving Nails: This isn’t strictly about the nail itself, but how it’s driven. With most siding, nails should be driven flush or slightly below the surface. For vinyl, they must be loose enough to allow expansion and contraction. An improperly set nail can lead to leaks, damage, or the siding coming loose. Your nailer’s depth adjustment is key here.
- Using Interior Fasteners Outdoors: Simply put, nails designed for indoor projects (like framing nails without coatings or standard common nails) will not survive the weather and will corrode.
