براغي ذات رأس أسطواني H76568 من HOLO-KROME M24-3 × 100mm | محرك سداسي | سبائك فولاذية مع أكسيد أسود حراري (10 / عبوة)

Finally got around to building a custom fixture and these M24-3 screws threaded in perfectly with zero binding. The black oxide finish on the alloy steel gives them a nice, durable look that should hold up well in the shop.

Replaced some worn jig bolts with these and the thermal black oxide finish has held up great against coolant splashes so far. The hex socket drive seated cleanly on my Allen key, no stripped edges out of the pack.

I’ve been using these socket cap screws for a few jig builds, and the hex socket drive makes tightening them in tight spots much easier than a standard hex head. The thermal black oxide coating has held up well against minor scuffs during assembly.
