براغي رأس كبس #1-14 × 3 بوصة | رأس مسطح مع محرك سداسي | ملولبة بالكامل | فولاذ سبائكي مع أكسيد أسود حراري (2 / عبوة)

Perfectly sized threads for my jig build, and the black oxide finish gave them a nice matte look that resists fingerprints. The flat head sat flush without any wobble, and the hex socket held up to a torque wrench without stripping. These will definitely be my go-to for precision work.

The hex socket drive on these screws is machined cleanly, so my Allen wrench gripped perfectly without any stripping during installation. They’re very solid for holding jig parts together, and the black oxide finish resists scuffs well.

The thermal black oxide finish is exactly what you want for tooling—no glare, no rust worries, and the hex socket grips the wrench with zero slip. Threads cut cleanly into the steel on my jig, and at this price for two, I’m already ordering more.
