Olivia ★★★★★

The hex socket drive on these set screws is perfectly machined, so my Allen key grabs tight without any wobble. They’re holding a pulley on my shaft firmly after a week of light use. Definitely a solid step up from the generic hardware I’d been using.

Miles C. ★★★★★

I was pleasantly surprised by the knurled cup point—it bit into the shaft much better than the smooth set screws I'd used before. These feel solid, and the black oxide finish hasn't shown any rust after a few weeks in a slightly humid shop.

Richard D. ★★★★★

Used these to lock a pulley onto a motor shaft and the knurled cup bit really digs in without stripping. The black oxide finish held up fine against some light oil and they seated cleanly with a hex key. Exactly what I needed for the price.
