The black oxide finish on these screws looks great and seems durable, and the hex socket drive made installation a breeze with my allen key. Every single one threaded perfectly into my tooling fixture without any binding or stripping.

Used these for a small jig I was building and the black oxide finish held up well against minor scratching during assembly. The hex socket drive made them easy to tighten without stripping, which I appreciate. They fit snugly in the M5 threaded holes with no wobble.

Threaded perfectly into my precision fixture without any binding, and the black oxide finish looks clean and professional. I’ve used a dozen so far and every single one seated flush with no deformation.
