Chloe W. ★★★★★

The black oxide coating on these M12 screws looks professional and held up perfectly under the torque wrench. They threaded smoothly into my tooling jig without any binding, and that 280mm length was exactly what I needed for the assembly.

Harper ★★★★★

I needed longer bolts for a jig I was building, and the 280mm length of these socket cap screws was exactly right for clamping thick plates together. The class 12.9 alloy steel feels robust, and the partial threading made installation straightforward.

Aurora ★★★★★

The black oxide finish on these M12 bolts gave them a nice uniform look, and the partial threading made alignment in my jig much easier than I expected. They tightened down smoothly with a hex key and held firm under load.
