Customer Reviews (4.6 / 5 · 5 reviews)

Riley U. ★★★★★

Used a handful of these so far in a jig build and the 40mm length was exactly what I needed for that assembly. The hex socket drive engages cleanly with no wobble, which made them quick to install.

Stella ★★★★★

The zinc plating is even and the threads are clean on every single one of the 200, which is exactly what I need for precision jigs. They seat flush in the countersink without any wobble, and the 10.9 alloy steel feels solid enough for heavy-duty tooling.

Eli ★★★★★

Needed a batch of fasteners for a jig I’m building, and the 10.9 grade alloy steel feels much sturdier than the cheap hardware store stuff. The flat head sits flush without needing to countersink.
