براغي ضبط بنقطة كأس بلاستيكية #1-8 × 1 بوصة | فولاذ سبائكي (25 / عبوة)

I've been using these to hold knobs on a jig I built, and the nylon cup grips the shaft without marring it like regular set screws do. The 25-pack is plenty for several projects.

The nylon pellet tip grips the shaft firmly without leaving a nasty gouge, which is exactly what I needed for a quick adjustment on a jig. Alloy steel feels solid, and the hex socket seated perfectly in my driver.

The hex socket drive made tightening these into a tight spot on my jig way easier than using a standard screwdriver. The nylon pellet tip holds firmly without scratching the shaft underneath. Exactly what I needed for a stubborn adjustment application.
