Customer Reviews (4.8 / 5 · 5 reviews)

Hazel ★★★★★

Finally got these for a project rebuilding some old machinery and the fully threaded design made alignment way easier than I expected. The 18/8 stainless is holding up great in a slightly damp shop environment.

Joshua ★★★★★

I was a bit skeptical about buying 900 of anything, but these hex head screws are uniformly threaded and the 18/8 stainless steel feels properly machined. Every single one I've used so far has seated cleanly without any tool slip.

Isabella ★★★★★

Used a few to mount some brackets on a 3D printer, and the hex heads let me get a socket on them in a tight spot. The stainless steel gives me confidence they won't rust out in the shop environment.
