براغي رأس مقبس مقاس #8-36 × 1-3/4 بوصة | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

Needed a set of precision fasteners for a jig I was building, and the partially threaded design on these made alignment much easier. The black oxide finish gives them a nice, durable look that should hold up well in the shop.

Grabbed a pack of these for a fixture on my milling machine, and the partially threaded shank made alignment much easier. The hex socket drive let me torque them down firmly without stripping.

The thermal black oxide finish handles well and hasn’t flaked during assembly, and the hex socket drive grips firmly without stripping. Threading into tapped holes in mild steel was smooth, though I wish the package included a few extras for the inevitable dropped ones.
