براغي كاب مقبس 1-1/4-7 × 20 بوصة | سداسي | خيط جزئي | سبيكة فولاذ أكسيد أسود حراري

The black oxide finish on these screws looks great and seems like it'll resist rust on my shop jigs. Threads were clean and the hex drive bit fit perfectly without any slop.

Needed a set of beefy fasteners for a heavy-duty press fixture, and the 20-inch length on these socket cap screws was exactly what I was after. The black oxide coating gave them a nice, clean look straight out of the box and seems like it'll hold up well.

Used a few of these in a jig setup last week and the thermally black oxide finish held up great under some serious clamping pressure. The hex socket drive seated perfectly with an Allen wrench, no stripping or wobble on the 20-inch length.
