براغي ذات رأس مقبس 1-8 × 6" | محرك مقبس سداسي | رقعة نايلون | خيط جزئي | فولاذ سبيكي مطلي بأكسيد أسود حراري (10 / عبوة)

The black oxide finish on these screws has held up perfectly during my recent jig build, and the nylon patch adds a nice touch of security. They threaded in smoothly with no binding even at that length.

The partially threaded design makes seating these in jigs a breeze, and the nylon patch holds them snug once torqued down. I've had them in a heavy fixture for two weeks now with zero loosening, which is exactly what I needed.

Installed these in a jig I’m building and the 6-inch length let me reach through a thick bracket without any trouble. The black oxide finish feels durable and hasn’t scratched during tightening.
