Description

The 2½‑inch Black Concrete Nails are heavy-duty fasteners engineered for secure anchoring into masonry surfaces like concrete, brick, and mortar. Forged from hardened high-carbon steel with a durable black finish, these nails resist corrosion while delivering impressive strength and shear resistance. Featuring a robust tapered or smooth shank and a flat, wide head, they are perfect for driving 2× lumber, furring strips, or fixtures directly into concrete without pre-drilling. The hardened tip is built to penetrate hard substrates with minimal bending or splitting. Whether you are installing base plates, attaching furring to block walls, or building concrete formwork, these nails offer reliable grip and long-lasting performance for both professional construction and home improvement projects.
