Riley S. ★★★★★

The knurled grip on these #4-40 set screws made them easy to handle even with oily fingers, and the cup point bit perfectly into my shaft for a solid lock. Came in a nice organized package of 100, exactly what I needed for a batch of repairs.

Carter ★★★★★

I needed some small set screws for a repair on a tight assembly, and these alloy steel ones fit perfectly with the hex drive. The threads are clean and the knurled cup point held firm under moderate torque.

Julian B. ★★★★★

The knurled cup point really grips well in my small adjustment applications—no slipping at all. These #4-40 screws are exactly the right size for a tight machine setup I’ve been working on, and the hex drive makes them easy to torque down.
