براغي غطاء مقبس 7/16-20 × 1 بوصة | رأس زر محرك سداسي المقبس | ملولبة بالكامل | فولاذ سبائكي مؤكسد أسود حراري (50/عبوة)

Ordered these for a jig I was building, and the hex socket drive made installation in tight spots much easier than using a standard hex head. The 50-pack is great value for the price, and the black oxide finish has held up well against some light oil and handling. They threaded smoothly into tapped

The black oxide finish on these is way darker and more uniform than what I usually get, so they look great on my jig build. All fifty threaded cleanly into tapped holes without a single binding issue, which is rare at this price point.

These button head screws fit perfectly into my jig setup, and the black oxide coating gives them a clean, professional look. The hex drive made installation quick without stripping. Exactly what I needed for precision assembly work.
