Customer Reviews (4.6 / 5 · 5 reviews)

Harper ★★★★★

The cup point bit into the shaft exactly where I needed it, and the hex socket gave me enough leverage to torque it down solid in a cramped spot. These 3.25-inchers are beefy enough to hold firm without stripping.

Samuel ★★★★★

These were spot-on for replacing the stripped adjustment screws on my mill's cross-slide. The 3 1/4" length and the cup point really bite into the shaft, so they hold tight even under heavy vibration. All 100 came in the package with sharp threads, no burs.

David S. ★★★★★

The hex socket drive gave me plenty of torque to seat these deep in a tight spot without stripping. Alloy steel feels plenty tough, and the cup point bit in nicely on the first go.
