10d X 3 In. Hardened Steel Tapered Masonry Nails (240 Ct., 5 Lb.)

Ideal for attaching wood members to cinder block walls as well as to fresh concrete. The blunt point and tapered shank cause minimal spalling during penetration and offer even greater pull-out resistance than wire masonry nails. 3/4" penetration is recommended. Safety glasses are recommended when driving these nails. Sizes: 1 lb., 5 lb., and 50 lb.
