Customer Reviews (4.8 / 5 · 5 reviews)

Owen H. ★★★★★

The serrated teeth on these hex heads really dig into the metal panel I was fastening, preventing any slipping while tightening. The zinc coating looks clean and should resist rust in my garage setup.

Owen ★★★★★

Put these in a steel bracket I was mounting to a concrete wall, and the serrated heads locked down tighter than standard bolts. The zinc coating looks clean and didn’t flake off when I torqued them.

Henry B. ★★★★★

The hex head on these grabs a wrench cleanly, and the serrated underside locks into the panel without spinning. Zinc plating looks even and should hold up fine in a dry garage. I ordered a hundred and every one threaded smooth.
