Customer Reviews (4.6 / 5 · 5 reviews)

Timothy Q. ★★★★★

Packed these into a precision fixture I'm building and the flat head sits perfectly flush every time. The 12.9 alloy steel feels seriously tough, and the zinc plating has a nice even coating that should resist rust well.

Chloe D. ★★★★★

The hex socket drive seated cleanly on my Allen key without any wobble, and the zinc plating looks uniform across all 400 pieces. I’ve used about 80 so far in a precision assembly and not a single one has stripped or fought the thread.

Riley ★★★★★

These fit perfectly in my jig setup, and the hex socket drive made installation quick with no stripping. The 12.9 alloy steel feels much tougher than the standard bolts I was using before.
