HOLO-KROME 73119 3/8-24 X 2-3/4" براغي رأس أسطواني بمقبس | محرك مقبس سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (50 / عبوة)

These bolts threaded in perfectly to hold a heavy jig plate, and the black oxide finish wiped clean of cutting oil without any fuss. Had to double-check the 50-count bag because they were packed so neatly.

Needed longer bolts for a custom fixture repair and these 3/8-24 x 2-3/4" socket caps fit exactly. The hex drive was crisp and the black oxide coating looks clean with no blemishes.

The black oxide finish on these screws is holding up well in my fixture setup, and the threads engaged smoothly even in tight spots. For the price per piece, this pack is a solid deal for tooling jobs.
