Customer Reviews (4.8 / 5 · 5 reviews)

Scarlett V. ★★★★★

The cup point tip on these screws held the nylon pellet securely while I torqued them down in a tight spot—no slipping at all. Solid build quality for the price, especially the alloy steel finish.

Emma G. ★★★★★

I needed a reliable set screw for a jig I was building, and the nylon pellet holds tight without marring the shaft underneath. The alloy steel feels sturdy, and the hex socket made it easy to get them snug in a cramped spot.

Samuel A. ★★★★★

The hex socket drive made installing these into a tight spot on my jig so much easier than using a regular screwdriver. They’re small but feel surprisingly sturdy for the price.
