Customer Reviews (4.8 / 5 · 5 reviews)

Isabella ★★★★★

I've been using these set screws on a milling fixture, and the nylon pellet really holds tight without marring the shaft. The cup point grips well even with frequent adjustments.

Samuel ★★★★★

The hex socket drive made it easy to tighten these set screws in a cramped bracket on my milling machine. The alloy steel feels sturdy, and the nylon pellet provides just enough grip without marring the shaft.

Robert ★★★★★

I needed a nylon pellet for a precise soft-lock application and these set screws fit perfectly—the alloy steel shank felt solid while turning with my hex wrench. Installation was quick on a tight jig, and they held adjustment without stripping.
