براغي تثبيت بنقطة كوب من النايلون مقاس 1/2-20 × 1" بمحرك سداسي داخلي | فولاذ سبائكي (100 / عبوة)

Needed to secure a fixture where vibration kept loosening standard screws, and these nylon pellets haven't budged after a week of runtime. The hex socket let me torque them down properly in a cramped spot without stripping.

The nylon pellet really locks into the workpiece without marring the surface, which is exactly what I needed for a repeated adjustment setup. All 100 screws in the package had clean threads and consistent cup points.

The hex socket drove in smoothly even in the tight spot behind my equipment stand, and the nylon pellet tip held firmly without marring the surface. Exactly what I needed for a precise adjustment stop.
