Michael I. ★★★★★

Grabbed these for a small robotics project and the flat point really holds its position without slipping under vibration. All 1000 were consistently threaded and the alloy steel feels plenty strong for my use.

Joseph ★★★★★

I was a little worried about stripping the hex socket on such a small screw, but the alloy steel held up fine across all 1000 pieces. The flat point seated cleanly in the set position every time, even when I had to adjust them twice.

Ava C. ★★★★☆

They did the job for a small robotics bracket I was securing, but a few screws had slightly uneven threads. The flat point seated perfectly in the dimples, which I appreciate for precise positioning. Good value for the quantity, though I wish the packaging was sturdier.
