Customer Reviews (4.8 / 5 · 5 reviews)

Avery ★★★★★

The flat point on these M3x4 set screws seats perfectly against my spindle shaft, and the hex socket drives true without stripping. They're exactly the right fit for replacing worn fasteners on my mini lathe.

Hannah ★★★★★

Finally, a set screw that stays put under vibration—the flat point gives a solid bite without marring the surface. Perfectly sized for my mini mill’s gib adjusters.

Victoria ★★★★★

The flat point seated cleanly in the bore without any wobble, and the threading engaged smoothly with just a hex key. I’ve already used a couple on a fixture and they’ve held their torque through a few setups. Solid little fasteners for the price.
