Zoe M. ★★★★★

The black oxide finish on these 12.9 alloy steel screws looks great and held up well in my jig build, no corrosion after a week of coolant splashes. The hex socket drive engages cleanly every time, and the fully threaded length is perfect for clamping thin plates together.

Eli X. ★★★★★

Used these to replace some worn bolts on an old jig and the black oxide finish actually makes them slide into tight spots easier. They’re exactly the right length for what I needed, and the hex drive seats perfectly without stripping.

Ryan M. ★★★★★

Installing these in a precision fixture and the hex socket drive felt perfectly snug — no stripping on the first few. The black oxide finish looks clean and consistent across all 400 pieces.
