Customer Reviews (5.0 / 5 · 5 reviews)

Eva ★★★★★

The black oxide finish on these screws hasn't chipped or worn at all after a week of heavy use in a jig setup, and the hex drive seated perfectly without stripping. Exactly the strength I needed for tooling.

Chloe R. ★★★★★

Used these to bolt down a heavy press fixture at work, and the hex socket drive made installation effortless even in tight spots. The 12.9 alloy steel feels incredibly sturdy under load—no sign of stripping or deformation so far.

Benjamin ★★★★★

The black oxide finish looks almost too clean to install—these really complete a jig build without any rough edges. Class 12.9 hardness felt solid from the moment the threads caught, and the 25mm length was spot-on for my fixture plates.
