براغي مقبس نقطة كوب نايلون 3/8-16 × 1-1/2 بوصة | سبيكة فولاذية (100 / عبوة)

The hex socket drive made tightening these in a tight spot on my milling machine so much easier than using a standard wrench. Alloy steel feels solid, and the cup point grips really well without marring the surface.

The nylon patch on these set screws holds tight even with vibration, which is exactly what I needed for a jig fixture. They threaded in smoothly with a hex wrench, no binding or galling.

The cup point tip sits perfectly flush against the surface, giving a clean, professional look. I’ve been using them in tight engine compartments and the hex drive makes installation a breeze, even with limited room to work.
