براغي رأس مقبس مقاس 2-BA × 3/8 بوصة بمحرك سداسي المقبس ملولبة بالكامل من الفولاذ السبائكي مع أكسيد أسود حراري (100/عبوة)

Installed a batch of these into a jig plate today and the hex socket engagement was crisp with no wobble. Threads started smoothly and torqued down consistently, exactly what I need for repeatable assembly work.

The hex socket drive grips the Allen key without any slipping, and the fully threaded length makes them a breeze for jigs that need a solid bite. Sharp threads, clean black oxide finish, and the whole hundred-count box came packed neatly with no duds.

These black oxide screws held up perfectly when I used them to secure a jig fixture on my milling table. The hex drive seated firmly without any stripping, and the threads engaged smoothly into the tapped hole. A solid choice for precision work.
