Sebastian ★★★★★

I’ve been using these socket cap screws for building custom jigs, and the black oxide finish has held up really well against minor scratches during adjustments. The M12x1.75 thread engages smoothly, and the hex drive seats perfectly, making installation easy.

Stella ★★★★★

The hex socket drive on these 20mm screws holds the bit securely without any wobble, which made installation on my jig fixture a breeze. For the price of a hundred pieces this Class 12.9 alloy steel feels seriously robust. I've already ordered another pack for future tooling projects.

Alexander ★★★★★

The black oxide finish on these M12 screws looks fantastic and holds up well on my jig fixtures. They thread smoothly with no binding, perfect for precision assemblies.
