براغي سوكيت سيت بنقطة كوب من النايلون 1/2-13 × 1-3/4 بوصة | سبيكة فولاذ (50/عبوة)

The nylon pellet tips on these set screws grip really well without marring the surface underneath. Used them for a jig adjustment and they held tight even with heavy vibration.

The hex socket drive made tightening these into a tight spot much easier than expected. The cup point tip and nylon pellet seemed to bite into the metal really well, holding firm under some vibration I tested. I’m impressed with the quality for the price, these will work great for my jig setup.

The nylon pellet tips held tight on my first test without damaging the shaft surface. These set screws are exactly what I needed for a delicate alignment job in a tight machine space.
