براغي غطاء مقبس 7/16-20 × 5/8 بوصة | محرك سداسي المقبس | ملولبة بالكامل | فولاذ سبائكي مع أسود حراري مؤكسد (100 / عبوة)

Used a whole bag replacing bolts on a jig fixture and every single one threaded in clean without any gunk in the hex socket. For a hundred pieces the alloy steel and black oxide feel properly done, and the 5/8" length fit my setup perfectly. My only surprise was how much heavier the bag felt than I

The black oxide finish on these screws makes them look sharp on my shop fixtures and seems to resist rust better than plain steel. I also appreciate that the hex socket drive let me torque them down without stripping the head.

I needed a full box of these for a jig I was building, and the 100-count pack is perfect for stocking up. The hex socket drive really grips the Allen key tightly without any wobble as I torque them down.
