براغي رأس مقبس 7/16-14 × 7/8 بوصة | رأس مسطح محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي مؤكسد أسود حراري (100/عبوة)

The black oxide finish is exactly as pictured—uniform and tough, no flaking during install. I grabbed these for a jig I’m building, and the flat head seats perfectly flush every time. For a hundred pieces at this price, the threading is impressively clean and consistent.

I’ve been using these flat head screws for jig assembly, and the hex socket drive makes installation really easy without stripping. The all steel construction feels solid, and they came exactly as the full threading described. Works perfectly for my precision tooling projects.

The black oxide finish on these screws looks great and seems durable, and the hex socket makes driving them into my tooling jig much easier than a slotted head. The full threading held tightly in the steel plate I'm working with. Exactly what I needed for a clean, professional assembly.
