Customer Reviews (4.6 / 5 · 5 reviews)

Aurora W. ★★★★★

Perfect fit for securing a small gear onto a 1/8” shaft, and the brass finish blends nicely with the rest of the assembly. The flat point really helps it bite into the shaft without marring the surface.

Adam F. ★★★★★

The brass finish on these set screws looks really clean against the nickel-plated collar I'm using. They threaded smoothly into the hole and hold the pulley tight without any wobble.

Miles ★★★★★

Just the right size for my small pulley setup, and the brass feels solid when I thread them into the collar. The flat point seats nicely against the shaft without marking it up, and the hex drive worked cleanly with a standard allen key. Pack of fifty means I've got spares for the next project.
