Customer Reviews (4.4 / 5 · 5 reviews)

Owen I. ★★★★★

These 1¾-inch set screws worked perfectly for locking a pulley onto a keyless shaft. The cup point gripped firmly without marring the surface, and the alloy steel feels solid enough for repeated adjustments.

Sophia ★★★★★

The hex socket drive on these set screws made installation in a tight spot much easier than I expected. The 1-3/4" length is perfect for my project, and the cup point really digs in for a secure hold.

Natalie ★★★★☆

These screws hold well in tight spots once you get the hex drive seated. The alloy steel feels solid, though a few in the pack had slightly uneven threads. Worked fine for my project overall.
