براغي مقبس نقطة كوب بحبيبات نايلون 5/16-18 × 3/8 بوصة | فولاد سبائكي (100 / عبوة)

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.

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.

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.
