Lily ★★★★★

The black oxide finish holds up way better than plated screws I’ve used before, and the hex socket drive seated perfectly with my Allen key. These M24s feel rock solid for the precision assembly work I do.

Kevin D. ★★★★★

Installed these in a jig fixture at work and the black oxide coating held up nicely against some light coolant exposure. The threads on all ten were clean and uniform, no binding at all during assembly.

Julian ★★★★★

The hex socket drive fit my torque wrench perfectly, and the black oxide finish on these M24 bolts really resists oils in my shop. They’ve been solid holding a jig together through constant vibration without any loosening.
