Eva I. ★★★★★

The hex socket drive engaged perfectly with my Allen key, making installation on a shaft clamp straightforward. Threads cut cleanly into the tapped hole without any binding. For the price, these cup point set screws are a great value for industrial projects.

Leo G. ★★★★★

Black oxide finish on these screws is perfectly even and should resist rust well in my machine tool applications. The hex socket drives cleanly without any wobble, and the cup point gives a nice flush fit in tapped holes. Glad I grabbed a full pack of 100 for upcoming projects.

Daniel ★★★★★

I needed cup point set screws for a shaft clamping job, and these fit perfectly with a nice tight hex socket drive. The 1/4-28 thread engaged smoothly, and the thermal black oxide finish seems durable enough to resist rust.
