Customer Reviews (4.6 / 5 · 5 reviews)

Ava P. ★★★★★

I've been using these for fixture builds and the Class 12.9 hardness really holds up under torque without stripping. The black oxide coating gives them a nice consistent finish that resists shop grime well.

Ryan ★★★★★

Installed these in a jig fixture today and the black oxide finish held up well against minor scuffs without any galling. The 18mm length works perfectly for clamping 6mm plate with a washer.

Penelope J. ★★★★★

Installing these in a tight jig was effortless because the button head sits flush without interfering with moving parts. All 600 screws in the pack have clean, consistent threads and the black oxide finish holds up well against minor abrasion. Exactly what I needed for tooling work.
