Henry C. ★★★★★

The hex socket drive made adjustments in my tight engine bay a breeze, and the knurled cup point tip held its grip perfectly. These screws feel solid and precisely machined for the application. Exactly what I needed for a high-torque setup.

Penelope H. ★★★★★

The zinc plating on these set screws looks clean and even, and the knurled cup point grips the shaft firmly without stripping. Used them to lock a pulley in place and they held through a full day of vibration. Exactly what I needed.

Owen ★★★★☆

Used these for a jig I’m building and the hex socket drive made adjusting them in a tight spot a breeze. The zinc plating looks clean and seems durable. Only tiny thing is I wish the package had a few extras for waste.
