Violet ★★★★★

Needed exact M2.5 threads for a RC car rebuild, and these flat head screws fit the counterbores perfectly. The black oxide finish looks nice and the Class 10.9 steel feels plenty strong for the small torque I'm applying.

Miles ★★★★★

I was replacing some worn-out fasteners on a jig, and these M2.5 screws seated perfectly in the hex socket without stripping. The black oxide finish feels robust, and the 10.9 alloy steel gives me confidence they'll handle the torque. A solid buy for precision work.

Ryan ★★★★★

These little black oxide screws fit perfectly into my jig’s threaded holes, and the hex socket drive made tightening them effortless. The 12mm length was just right for the assembly, and the 900-count box means I have plenty left for future projects.
