هولو-كروم 72196 براغي رأس سداسية مقاس 7/16-14 × 1-1/4 بوصات | محرك سداسي | فولاذ سبائكي بأكسيد حراري أسود (50 / عبوة)

Installed these on a jig I’m building and the black oxide finish hasn’t chipped or scratched at all during assembly. The hex socket drive makes tightening them down much easier than a standard hex head would.

Needed a solid batch of cap screws for some custom jig work, and these 7/16-14s are holding up perfectly under tightening torque. The hex socket drive grabs the wrench cleanly with no slipping.

The black oxide coating on these screws has held up perfectly during a recent jig assembly project, and the hex drive seated firmly without any stripping. They're a solid choice for precision tooling work.
