براغي رأس كوبية بنقطة بلاستيكية 5/8-11 × 5/8 بوصة | فولاذ سبائكي (50/عبوة)

I needed a set screw that wouldn't mar a shaft when tightened, and the nylon pellet on these handles that perfectly. They drive easily with a hex key into tight spots, and the alloy steel feels solid.

The nylon pellets on these set screws hold fast without marking the shaft—perfect for my jig setup. They threaded smoothly into the 5/8-11 hole and stayed put under vibration. Exactly what I needed for a clean, adjustable hold.

The hex socket drive let me get these set perfectly flush in a tight jig, and the cup point tip grabs just right without stripping. Really solid alloy steel feel for the price.
