براغي تثبيت سداسية بنقطة كوب من النايلون 1/4-28 × 1 بوصة | فولاذ سبائكي (100 / عبوة)

The nylon pellet tip is exactly what I needed to hold adjustment knobs without marring the shafts, and the hex socket makes them a breeze to tighten even in cramped spots. These feel solidly made, and the 100-count pack will last me ages.

I needed a screw with a soft tip that wouldn't mar a shaft, and these cup-point nylon pellets hold securely without slipping. The hex drive made installation in tight spots much easier than a slotted head would have.

The nylon tip on these set screws prevents marring yet still holds firm under vibration on my jig. Pack of 100 gives plenty of extras for future projects.
