براغي رأس كبس مقبس سداسي | 1-8 × 2-1/2" | صنع في الولايات المتحدة | فولاذ سبائكي أكسيد حراري أسود (10/عبوة)

Swapped out the cheap Chinese bolts on my press jig for these — the black oxide finish hasn't chipped at all after a week of tightening and loosening. They thread cleanly into the tapped holes without any binding.

These hold up perfectly on my milling machine’s indexing head—the hex drive seated firmly without stripping. The black oxide finish seems durable, and getting a true USA-made set at this price is tough to beat.

Used a set to replace worn bolts on a jig press, and the black oxide finish hasn't chipped at all after a week of heavy use. Fit perfectly into the hex socket without any wobble.
