Customer Reviews (4.8 / 5 · 5 reviews)

Ella R. ★★★★★

The flat underside of the hex head sits flush and grips well with a socket, and the zinc coating looks clean and uniform across all 500 screws.

Nicholas ★★★★★

I needed exactly these M5-0.8 x 20mm cap screws for a small assembly project, and the hex head made them easy to drive with a socket wrench. The zinc coating looks clean and should resist rust well in my workshop environment.

Julian G. ★★★★★

The zinc plating on these M5 bolts is uniform and bright, so they look clean on the machinery I’m assembling. The hex heads grip the socket wrench firmly without any stripping, and having 500 on hand means I’m set for the next few projects.
