Owen ★★★★★

Finally got to torque these into a heavy jig frame and the 12.9 alloy steel held perfectly without any stretch. The black oxide finish also slid into the tapped holes smoothly without galling.

Ella Z. ★★★★★

After test fitting these in a precision fixture, the hex socket drive gave excellent torque transfer without any cam-out. The black oxide finish seems durable and consistent across all 25 pieces.

Zoe Z. ★★★★★

I needed a 100mm length for a custom jig, and the fully threaded portion down from the head made installation easier. The black oxide finish on these M20 screws feels very durable and hasn't shown any wear after tightening.
