Customer Reviews (4.6 / 5 · 5 reviews)

Jason ★★★★★

I used these M6 screws to replace some worn fasteners on a jig, and the 18/8 stainless steel feels noticeably sturdier than the old ones. The partial threading made alignment much easier during assembly.

Samuel ★★★★★

I was a bit worried about getting the thread pitch right for my jig, but these M6-1 x 40mm screws threaded in smoothly on the first try. The 18/8 stainless steel feels solid and corrosion-resistant, and having 200 in a pack means I won't run out mid-project.

Natalie C. ★★★★★

I needed a bulk set of hex socket screws for my jig builds, and the 18/8 stainless steel on these feels solid enough for repeated tightening. The 40mm length worked perfectly for securing a thick fixture plate without bottoming out, and the partially threaded shank gave me a cleaner grip.
