HOLO-KROME 76842 براغي رأس مقبس M14-2 × 70mm | محرك مقبس سداسي | سبيكة فولاذ أكسيد أسود حراري (25 / عبوة)

Had to swap out some worn bolts on a milling fixture, and these M14-2 x 70mm screws threaded in smooth as butter. The thermal black oxide finish seems really durable, too.

The hex socket drive seated perfectly on my driver without any wobble, and the thermal black oxide finish has held up through three weeks of daily use on my jig. I’d buy these again for any precision assembly work.

The black oxide finish on these screws is nice and even, and the hex socket drive makes tightening them in tight spaces much easier. I used them to repair a workbench clamp and they held perfectly.
