Samuel ★★★★★

The knurled cup point tip bit into the shaft exactly where I needed it, and the zinc plating already held up to a week of oily shop use without a speck of rust. For a hundred pieces at this price, I’ve got spares for every future job.

Robert G. ★★★★★

The hex socket drive let me torque these set screws down in a really tight spot on a machine base, and the knurled cup point grabbed the shaft firmly without slipping. They feel sturdy and well-made for the price.

Samuel P. ★★★★★

The knurled cup point bites into the shaft exactly where I needed it, and the hex socket drive made torquing them down in that cramped bracket a breeze. All 100 came clean with no damaged threads, zinc plating looks consistent across the batch.
