براغي ذات رأس مقبس 7/16-14 × 1-1/4 بوصة | محرك سداسي | صناعة أمريكية | فولاذ سبائكي مع أسود حراري (750 / عبوة)

The hex drive on these screws grabbed the bit perfectly, with no stripping or cam-out during assembly. The black oxide finish looks consistent across all 750 pieces, and they’ve held up well in my jig builds.

Packed 750 of these in one box with no damage—the black oxide finish looks uniform and holds up well against oil. I used them for securing a jig on the mill, and the threads engaged smoothly without any binding.

The hex sockets are machined cleanly, so my Allen key seats perfectly every time without any wobble or stripping. I've used about two hundred on a fixture build so far and the black oxide finish has held up great through assembly and handling.
