What Is a Wire Nail?
Wire nails, common in wooden structures and home DIY projects, are a prevalent type of nail.
Made from iron, wire nails are produced from iron wire. They feature a dish-shaped head with mesh and a sharp tip for piercing wood.
Typically, wire nails are divided into two categories: those for hand hammers, packaged separately, and those for nailers, linked together in coils.
Uses of Wire Nails
Wire nails are versatile, primarily used to fasten or join wood pieces in construction and DIY projects.
In house foundation work, wire nails play a crucial role in setting up formworks for concrete pouring. Their smooth, clean bodies allow for easy removal post-construction, making them ideal for both constructing and dismantling formworks.
Principle of Wire Nails
Also known as N nails, their sizes range from N19 to N150 as per JIS standards, with the number indicating length; shorter nails are thinner, and longer ones are thicker.
In wood-frame construction, particularly in post and beam frameworks, N50 nails are commonly used. They are essential in constructing high-strength load-bearing walls, with N50 nails spaced at 150 mm intervals in structural plywood of at least 7.5 mm thickness.
For quality checks post-construction, color-coded N nails (Digi-N nails) with the nail length marked on the head are utilized, enabling inspection of building strength.
It’s important to note that N nails are suitable for load-bearing walls in wood frame construction, but not in frame wall construction (2×4 construction).
