Abigail ★★★★★

The hex socket drive makes installation quick and clean, and the 250-pack covers multiple projects easily. These screws hold components firmly in place without any wobble. Exactly what I needed for securing parts on a shaft assembly.

Harper E. ★★★★★

Installed a few of these on a motor shaft to lock down a pulley, and the hex socket drive made it easy to torque them just right. The box of 250 will last me through plenty of projects.

Lily Y. ★★★★★

Packed 250 in a sturdy little box, these hex drive set screws are exactly what I needed for locking down a pulley on a motor shaft. The threads cut cleanly and they hold firm without stripping.
