براغي رأس مقبس 3/4-10 × 1-1/2 بوصة | محرك سداسي | صنع في الولايات المتحدة | فولاذ سبائكي مؤكسد أسود حراري (25/عبوة)

Used a set to secure a heavy-duty fixture on my milling machine, and the hex socket drive made installation a breeze even in tight spots. The black oxide finish looks quality and seems like it'll resist rust well.

Installed these in a jig at work and they seated perfectly with no wobble. The hex socket drive grabbed cleanly with no stripping, and the alloy steel feels solid. USA-made quality shines through.

The black oxide finish on these screws is perfectly uniform, and the hex drive fits my Allen wrench like a glove. I used them to secure a heavy jig in my shop, and they held firm with zero stripping. Exactly the quality I expect from USA-made alloy steel.
