براغي كاب مقبس 1-8 × 5 بوصة | محرك مقبس سداسي | صنع في الولايات المتحدة | فولاذ سبائكي بأكسيد أسود حراري (10/عبوة)

The black oxide coating on these screws resists rust perfectly for my workshop jig. The hex drive seated firmly without stripping on the first use.

The black oxide finish on these screws is nicely uniform and seems durable enough for repeated adjustments on my drill jig. Threads cut cleanly into the pilot hole without any binding. Exactly the heavy-duty length I needed for a tight assembly.

I needed longer fasteners for a jig I was building, and these 1-8 x 5" socket cap screws fit the bill perfectly. The hex socket drive grabbed cleanly without any stripping, and the thermal black oxide finish looks great against the steel.
