براغي هولوكروم 72334 مقاس 3/4-10 × 7 بوصة برأس أسطواني | محرك سداسي | فولاذ سبائكي مؤكسد حراري أسود (10/عبوة)

I needed a heavy-duty fastener for a jig I’m building, and these 3/4-10 x 7" screws came with a perfect hex socket drive that gave me full torque control. The black oxide finish looks durable and hasn’t shown any wear after tightening.

The thermal black oxide finish looks great on my machine tooling, and the alloy steel feels plenty stout for the heavy jigs I’m building. Threads ran clean with no binding right out of the package, which saved me a headache.

These clamped down a jig I’ve been fighting with for weeks, and the black oxide finish hasn’t shown a single scratch after repeated tightening. The hex socket drive seated perfectly with my wrench, no stripping at all. Solid hold for the price.
