Customer Reviews (4.8 / 5 · 5 reviews)

Richard K. ★★★★★

Needed a strong set screw for a motor shaft repair, and these knurled cup points really bite into metal without slipping. Zinc plating looks clean and should hold up fine in my shop environment.

Claire D. ★★★★★

Used these to secure a pulley on a small motor shaft, and the hex socket made installation in that cramped space a breeze. The alloy steel feels tough, and the zinc plating looks clean.

Brian V. ★★★★★

Knurled cup point really grips the shaft without marring it, which is exactly what I needed for a locking collar setup. The zinc finish looks clean and the hex socket gives a solid bite even in an awkward angle under the machine.
