Customer Reviews (4.8 / 5 · 5 reviews)

Michael Y. ★★★★★

Installed these on a lathe steady rest and the hex socket made it easy to tighten in tight spots without stripping. The zinc coating looks clean and should hold up well in the shop.

Ella D. ★★★★★

The cup point really bites into the shaft—I used a handful on a gear hub and they haven't budged under vibration. Zinc plating looks clean, and the hex socket takes an Allen wrench without stripping.

Lily M. ★★★★★

Used a dozen of these to secure a pulley on a motor shaft and the cup point really bites into the metal without stripping. The zinc plating looks clean and the hex socket gave me plenty of torque with a small allen key. Exactly the size I needed for a tight fit.
