Chloe ★★★★★

The hex socket drive made cinching these down in a cramped spot way easier than I expected, and the alloy steel feels solid through and through. The knurled cup point grabbed the shaft firmly on the first try, no slipping even under load.

Eva R. ★★★★★

The knurled cup point really bites into the shaft, so these set screws hold firm even under vibration. All 100 pieces were cleanly threaded and the alloy steel feels plenty tough for my machinery adjustments.

Harper L. ★★★★★

Getting these installed in a tight spot under my workbench was a breeze thanks to the hex socket drive, and the knurled cup point really grabs and holds position.
