How To Choose The Best Coil Nails For Your Fence

Aug 10, 2023 | NEWS

Building a solid, long-lasting fence starts with the right fasteners. Fence nails secure all the components together and transfer loads between boards and rails. For wood fences, 2 inch coil nails are an effective and convenient option. Here are the factors to consider when selecting coil nails for your fence.

Length Of Nail For Fences

The length of coil nails for fencing depends mainly on the thickness of the boards you’re joining. For horizontal boards that are 1.5 inches thick or less, you’ll generally want 2 inch long nails. This ensures the nail penetrates fully through both layers of boards for a secure hold.

For thicker boards around 2 inches, opt for nails around 2.5 inches long. When in doubt, go a little longer to make sure the nail exits the second board. Too-short nails may not fully grip both layers of wood.

Gauge Of Coil Nails

  • The gauge of coil nails indicates their thickness. For most wood fences, either 18 gauge or 20 gauge nails work well.
  • 20 gauge nails are thinner and more flexible, ideal for softer woods like cedar and fir. They’re easier to set flush to avoid snagging.
  • 18 gauge nails are heavier-duty. They’re better for dense hardwoods and pressure-treated lumber. The thicker shaft resists bending and pulling loose.

Head Style About Fence Nail Heads

Fence nail heads come in several styles:

• Smooth: Allows you to drive the nail fully flush for a low profile. Best for hidden applications.
• Ring shank: Has grooves that grip into wood. Provides more holding power but protrudes above the surface.
• Spiral: Similar grip to ring shank nails. May protrude slightly.

For aesthetic fences, smooth or straight shank nails driven flush work best. For heavy duty use, ring and spiral shank nails offer more durability.

Coating Of Nails

Galvanized and ceramic coated nails resist corrosion the longest for outdoor use. Stainless steel nails offer the highest corrosion resistance and strength but come at a premium price. For pressure-treated lumber, look for nails specifically approved for ground contact.

Material Of Most Common Fence Nails

Most common fence nails are made of hardened carbon steel wire for strength. Stainless options provide better resistance to rust and staining but are more expensive.

Other Options For 2 Inch Coil Nails

While 2 inch coil nails for fences cover the basics, these alternatives offer benefits for some applications:

• Brads: Shorter nails for joining trim and battens.
• Staples: Used for attaching wire mesh and chain link fences to wood posts.
• Screws: Provide more clamping power for lap joints but are slower to install.

For typical wood fences, start with 2 inch 20 or 18 gauge galvanized coil nails for a balance of performance and value. Choose spiral shank nails for extra holding power. Longer 2.5 inch nails work better for thicker boards. You can always upgrade to coated or stainless nails if corrosion resistance is a high priority. By considering these factors, you’ll be able to select the best coil nails to securely fasten all the components of your new or repaired fence.
