Customer Reviews (4.8 / 5 · 5 reviews)

Lily ★★★★★

Used these to attach some brackets to steel framing, and the self-drilling tip went right through without any pre-drilling or pilot holes. The hex head gripped nicely with a socket driver, and the stainless finish looks clean and won't rust.

Abigail ★★★★★

I needed these for a quick metal roofing repair and the self-drilling tip saved me a step since it bit right through without a pilot hole. The hex head held tight with my impact driver and the 18/8 stainless seems like it will resist corrosion well. Definitely worth the price for a hundred pack.

Hazel K. ★★★★★

These hex heads grab a 10mm socket perfectly and the self-drilling tip goes through 1/8" steel without any pilot hole. Used a full box on a rack project and didn't have a single strip-out.
