براغي رأس أسطواني 1/4-28 × 7/8" | محرك سداسي منخفض الرأس | فولاذ سبائكي أكسيد أسود حراري (100 / عبوة)

I needed a batch of precise screws for a jig I'm building, and the hex socket on these is clean and engages the bit without any wobble. The black oxide finish looks uniform and should resist rust in my shop.

The low head profile cleared my fixture plate where a standard cap screw would’ve bottomed out, and the black oxide finish came out of the box evenly coated, no chips. Threads ran smooth through my tapped holes without needing a chase. These are going into my jig builds from now on.

The hex socket drive seated perfectly with my Allen wrench and the black oxide finish looks sharp against the steel jig I'm building. These feel solid and precise, threading in smoothly every time. I'll definitely be ordering another pack for the next project.
