Concrete steel nails 100pcs

“Concrete steel nails” are specialized fasteners designed to penetrate and hold securely in extremely dense materials like concrete, cinder block, brick, or masonry.

The 100-piece count is a very common commercial size for these nails, often sold in a small box or pack.

Key Features of Concrete Steel Nails:

1. Material and Hardness: They are made from high-carbon steel and are heat-treated (hardened and tempered). This prevents them from bending or breaking when being driven into hard, abrasive surfaces.

2. Shank Design: Unlike common wood nails, concrete nails often have a fluted, ribbed, or spiral shank instead of a smooth one. This provides superior grip and holding power inside the masonry.

3. Finish: They are frequently galvanized (zinc-plated) or coated to resist rust, which is important when fixing to damp concrete.

4. Length: They come in various lengths, typically ranging from $1$ inch ($25\text{mm}$) to $4$ inches ($100\text{mm}$), depending on the required penetration depth for the base material.
