براغي رأس مقبس #3/4-10 × 5-3/4 بوصة | محرك مقبس سداسي | خيط جزئي | سبيكة فولاذ بأكسيد حراري أسود (10 / عبوة)

Needed some heavy-duty bolts for a press jig, and these 3/4-10s held up perfectly during assembly. The thermal black oxide finish looks professional and resisted scratching when I torqued them down.

These bolts threaded smoothly into the jig I’m building, and the black oxide finish holds up nicely to shop grime. The hex socket gave a solid, no-slip grip with my Allen wrench, and the partial threading made alignment easy.

I needed some black oxide fasteners for a jig rebuild, and the 5-3/4" length was exactly what I couldn't find locally. The hex socket drive engaged perfectly with my Allen key, and the thermal black oxide finish seems tougher than standard black oxide.
