The #8-3/4"zinc-plated, self-drilling screws feature a #2 drill point to give them penetrating power with a greater capacity for fastening heavier gauges of sheet metal. The undercut washer always seats flush. The full 1/4" (no. 8) head will not strip out of hex driver opening, and one 1/4" hex driver accommodates all sizes.
