Customer Reviews (5.0 / 5 · 5 reviews)

Harper V. ★★★★★

Installed a full batch of these into a jig plate and the cup point bit into the metal without slipping. They hold adjustment perfectly under vibration, and the hex socket made it easy to get good torque in a cramped spot.

Madison ★★★★★

Tightening these into a machine base was a breeze—the cup point bit into the steel cleanly and held firm even after a full day of vibration. The 55mm length gave me just enough reach without any wobble, and the alloy steel feels tough enough to trust for repeated adjustments.

Miles ★★★★★

The hex socket drive made torquing these down in a cramped gearbox a breeze, and the cup point bit into the shaft without any slipping. All 50 in the pack had clean threads and worked right out of the box, which is more than I can say for some pricier sets I've used.
