براغي ذات رأس أسطواني 1-8 × 2-1/4 بوصة | محرك سداسي | صنع في الولايات المتحدة | فولاذ سبائكي مع أكسيد أسود حراري (40 / عبوة)

I needed longer screws for a jig I was building, and these 1-8 x 2-1/4" socket cap screws fit perfectly without stripping. The hex socket drive made installation a breeze.

The black oxide finish on these is what sold me, and they thread in smoothly without any galling on my fixture plates. The hex socket drive grips the Allen key perfectly, no wobble, and the 40-count pack covers a whole build without a trip back to the supply house.

The black oxide finish is holding up well in my tooling fixture, and the hex drive seated snugly without stripping. Threads were clean and consistent across all forty screws. Only wish the packaging had a reusable lid to keep the extras organized.
