Customer Reviews (4.6 / 5 · 5 reviews)

Riley ★★★★★

These screws fit perfectly in the tight space behind my milling machine’s adjustment plate, and the hex drive let me torque them down securely without stripping. The knurled cup point held firm against the shaft, making alignment a breeze.

Miles S. ★★★★★

The knurled cup point grabbed the shaft firmly without stripping, even with repeated adjustments. For a hundred of these in zinc-plated alloy steel, the price feels fair. They’re holding tight in my jig so far.

Joshua ★★★★★

The hex socket drive made tightening these in a tight spot a breeze. They fit perfectly in my jig and held firm under load.
