Timothy N. ★★★★★

The knurled cup point bites into the shaft perfectly without slipping, even with a quick hex wrench adjustment. These M3 set screws held tight on a small motor mount I’ve been tweaking, and the alloy steel feels sturdy for the price.

Andrew A. ★★★★★

Used these on a robotics jig where space was tight—the hex socket drive made adjusting them a breeze even in awkward spots. The pack of 1000 is great value for prototyping.

William ★★★★★

The knurled cup point tip on these M3 screws gives a really solid grip during assembly, and I appreciate how the hex socket lets me torque them down precisely in cramped spots. They feel tough enough for repeated adjustments, and a thousand pieces means I won't run out anytime soon.
