Customer Reviews (5.0 / 5 · 5 reviews)

Joshua ★★★★★

The flat hex socket drive made tightening these into my tooling jig much easier than I expected. The zinc coating looks durable and the 12.9 alloy steel feels really solid for the price.

Stella ★★★★★

I used these for a jig fixture I’m building, and the flat head sits perfectly flush in the counterbore. The 12.9 alloy steel feels sturdy enough for the heavy clamping forces I need.

Benjamin P. ★★★★★

The zinc plating is flawless across all 25 pieces, and the 12.9-grade steel feels dense and reassuring in the hand. I used them to rebuild a press jig and the threading engaged cleanly without any galling.
