Hardie plank siding is a popular choice for homeowners due to its durability and aesthetic appeal. When it comes to installing Hardie plank siding, selecting the appropriate nails is crucial to ensure a secure and long-lasting installation. In this guide, we will explore the specific nails suitable for Hardie plank siding, their features, and the best practices for installation.

1. Nail Types for Hardie Plank Siding:

a. Stainless Steel Nails:
Stainless steel nails are highly resistant to corrosion, making them an ideal choice for Hardie plank siding installations. They are durable and provide excellent weather resistance, ensuring the siding remains securely fastened over time.

b. Hot-Dipped Galvanized Nails:
Hot-dipped galvanized nails are coated with a layer of zinc, offering good corrosion resistance. These nails are cost-effective and suitable for areas with moderate exposure to the elements.

c. Electro-Galvanized Nails:
Electro-galvanized nails are coated with a thinner layer of zinc compared to hot-dipped galvanized nails. They are suitable for interior applications or areas with minimal exposure to moisture.

2. Nail Size and Shank Type:

a. Nail Length:
The length of the nail depends on the thickness of the Hardie plank siding. For 1/4-inch thick siding, use nails that are at least 1-1/2 inches long. For 7/16-inch thick siding, opt for nails that are 1-3/4 to 2 inches long.

b. Shank Type:
Ring-shank nails or nails with serrated threads offer better holding power compared to smooth-shank nails. The threads grip the siding material tightly, preventing the nails from backing out over time.

3. Installation Tips:

a. Nail Placement:
Nails should be driven into the studs or sheathing, ensuring they penetrate at least 1 inch into solid wood. Proper placement prevents the siding from sagging or warping.

b. Spacing:
Space the nails approximately 16 inches apart horizontally along each stud. For vertical joints, nails should be spaced 12 inches apart.

c. Avoid Over-Driving:
Avoid over-driving the nails, as this can damage the siding material. Nails should be driven flush with the surface of the Hardie plank without crushing or cracking the material.

d. Pre-Drilling:
In areas near the edges of the siding panels, pre-drilling may be necessary to prevent splitting. Use a drill bit slightly smaller than the nail diameter for pre-drilling.

Conclusion:

Choosing the right nails for Hardie plank siding is essential for a secure and enduring installation. By selecting nails made from corrosion-resistant materials, choosing appropriate sizes and shank types, and following proper installation techniques, homeowners and contractors can ensure that their Hardie plank siding remains intact and visually appealing for years to come.
