Customer Reviews (4.4 / 5 · 5 reviews)

Timothy D. ★★★★★

Needed a few of these to secure a pulley to a shaft and the alloy steel feels plenty durable for the job. The flat head sits flush as expected, and the socket drive made installation quick with an Allen key.

Ellie W. ★★★★★

The hex socket drive is a nice touch for tightening these down with an Allen key, and the flat head sits flush on the pulley I mounted. They feel sturdy and held firm on the shaft without any wobble.

Isabella ★★★★★

Picked up these set screws for securing a pulley on a small shaft project, and the flat point design held perfectly without marring the surface. The alloy steel feels solid, and having 50 in the pack means I won't run out for a while.
