براغي رأس مقبس مقاس 5/16-24 × 3/4 بوصة برأس مسطح محرك سداسي المقبس مع كتلة نايلون ملولبة بالكامل من الفولاذ السبائكي مع أكسيد أسود حراري (100/عبوة)

The hex socket drive on these screws made installation a breeze with my Allen wrench. The black oxide finish looks professional on my tooling fixture, and all 100 pieces arrived clean and well-packaged.

The nylon pellet locking feature kept these socket cap screws perfectly in place on my drill jig after hours of use. The hex drive made seating them flush a breeze, and the black oxide finish looks professional against the steel plate.

Had to tighten some jig fixtures at the shop and these nylon pellet screws held fast without backing out, even under vibration. The black oxide finish already looks like it’ll resist rust better than the plain steel ones I used before.
