براغي ذات غطاء مقبس 1-1/8-7 × 6" | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي بأكسيد حراري أسود (2/عبوة)

The black oxide finish on these 1-1/8-7 x 6" screws is really tough and holds up well under repeated wrenching in my tooling fixtures. They threaded smoothly into tapped holes without any binding.

The black oxide finish gives these a clean, professional look, and the 1/8-7 threading cut into my steel fixture without any hassle. They’re solid for jig work, though I wish they came with a touch more length for thicker setups.

I needed beefy fasteners for a heavy-duty jig I was building, and these partially threaded screws held up perfectly under high torque. The thermal black oxide coating gives them a nice, tough finish that resists surface rust when I use cutting oil.
