براغي رأس كبس 3/4-10 × 14 بوصة | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي مع أكسيد أسود حراري

My milling machine was down for a week waiting on fasteners, but these screws fit perfectly and the black oxide finish feels tough. They threaded into the tapped holes with zero binding and I can already see they’ll hold up to repeated use. One less headache to deal with.

Installed these on a heavy-duty jig I’m building, and the 3/4-10 thread held perfectly under torque. The partially threaded length gave just the right grip without bottoming out.

The black oxide finish on these screws is holding up fine so far, and the hex socket drive made installation straightforward with a long Allen key. Took off one star because the partially threaded section was slightly longer than I expected for a 14" length, but they’re solid for my jig build.
