Customer Reviews (4.8 / 5 · 5 reviews)

Julian V. ★★★★★

Put these in a jig that sees constant vibration and the cup point really bites into the shaft—no loosening after a week. The hex drive lets you get them torqued down properly even when space is tight.

Scarlett ★★★★★

Had to secure some heavy-duty brackets on a lathe, and these set screws held firm without stripping. The 2 1/4" length gave me plenty of bite into the threads, and the cup point really gripped the shaft.

Andrew ★★★★★

The hex socket drive made installing these in a tight spot under my workbench effortless. The cup point tip seated perfectly without stripping, and the alloy steel feels solid. Exactly the right length for my project.
