Customer Reviews (4.8 / 5 · 5 reviews)

Riley ★★★★★

Used these to fasten a steel bracket to some thin gauge metal, and the self-drilling tip zipped right through without any pilot hole. The #12-24 thread bit in nice and snug, and the flat head sat flush so the phillips driver didn't strip a single one out of the hundred.

Abigail ★★★★★

Used these to attach a metal sign to a steel frame, and the self-drilling tip saved me from having to pre-drill a single hole. The zinc plating seems like it will hold up fine outdoors, and the 100-count box is a solid value for this size.

Robert ★★★★★

Had to fasten some metal brackets to a heavy steel beam, and these Tek screws drove straight in without any pre-drilling needed. The flat head sat flush perfectly, and the zinc coating gave them a clean look that should hold up fine outdoors.
