براغي رأس مقبس 5/8-11 × 2-3/8 بوصة | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي مؤكسد أسود حراري (25/عبوة)

The black oxide finish on these screws feels more durable than the plain zinc ones I’d been using, and the hex socket drive made installation a breeze with my Allen wrench. They fit perfectly in my drill press jig, and the 25-pack should last me through several projects.

Installed these in a heavy-duty jig at work and the threads cut cleanly without any binding. That black oxide finish gives them a nice, consistent look and seems to resist surface rust well. Really solid feel for the price.

The hex socket drive on these screws grabs really well, making installation a breeze even in tight spots. They feel solid and well-made for machinery uses, and the black oxide finish looks professional. I'm happy with how they hold up under heavy use.
