براغي ذات رأس أسطواني 5/8-11 × 1-3/4 بوصة | محرك سداسي منخفض الرأس | فولاذ سبائكي مع أكسيد أسود حراري (50/عبوة)

I needed these for a jig I was building, and the low head profile let me fit them in a tight spot where a standard cap screw would have hit the workpiece. The hex socket drive took a lot of torque without stripping, which was a relief.

The black oxide finish held up perfectly when I used these for mounting heavy jig hardware, no thread galling at all. I’ve already ordered another pack for future tooling projects.

Needed a low profile screw for a tight clearance on a tooling fixture, and these 5/8-11 caps fit perfectly without binding. The black oxide finish looks clean and the hex socket drove smoothly without stripping.
