HOLO-KROME 72208 براغي رأس مقبس 7/16-14 × 2-3/4 بوصة | محرك سداسي | فولاذ سبائكي أكسيد أسود حراري (25/عبوة)

Installed these in a jig fixture and the full threads made engagement easy. The 2-3/4 inch length gave me just the right grip for my assembly.

I needed some longer cap screws for a custom jig I’m building, and these 2-3/4" length with the hex socket drive made installation much easier than using a hex key on a shallow head. The black oxide finish hasn’t shown any wear after the first few disassemblies.

The black oxide coating on these screws slid right into my jig without any binding. They feel much more solid than the standard hardware I was using before. Exactly what I needed for my tooling setup.
