براغي رأس أسطوانية 1/4-20 × 2-1/2 بوصة | رأس منخفض محرك سداسي | ملولب بالكامل | فولاذ سبائكي مؤكسد أسود حراري (100/عبوة)

The hex socket drive sits flush without stripping, and the fully threaded length made dialing in tight tolerances on my jig super easy. The thermal black oxide gives them a clean, consistent look that’s held up well so far.

The thermal black oxide finish on these screws is surprisingly durable—handled them a lot during assembly and none scuffed or stripped. The low head profile fit perfectly in tight spots on my tooling setup, and the hex drive seated cleanly every time.

I needed these for a jig I was building and the fully threaded shank made tapping them to different lengths effortless. The black oxide coating looks professional and seems like it will resist rust well in my shop.
