Penelope ★★★★★

The cup point bites into the shaft like a champ, and these alloy steel screws held up through a full day of heavy adjustments without stripping. Length was spot-on for my 4-inch deep application, and the hex drive gave me solid torque in a cramped spot.

Steven I. ★★★★★

These set screws were exactly what I needed for a jig I was building; the hex socket drive made it easy to tighten them securely in a tight corner. The cup point tip held firmly without stripping, and the alloy steel feels solid. Very happy with the quality for the price.

Leo U. ★★★★★

I needed a sturdy screw for an old machinery repair, and the hex socket drive made it so much easier to torque down in that cramped spot. The alloy steel feels tough, and the cup point really helped hold everything together without stripping.
