براغي كاب مقبس 5/8-18 × 2" | محرك مقبس سداسي | صنع في الولايات المتحدة | فولاذ سبائكي أكسيد أسود حراري (225/عبوة)

Installed these on a press fixture today and the alloy steel held torque beautifully with zero stripping. The black oxide finish is consistent across all 225 pieces, which saves time checking each one.

The hex socket drive on these 5/8-18 x 2" screws makes tightening them in tight jig spots way easier than I expected. The thermal black oxide finish feels consistent across all 225 pieces, and they’ve held up fine under heavy clamping pressure so far.

I needed a batch of heavy-duty fasteners for a fixture jig, and these 5/8-18 x 2" socket cap screws threaded in perfectly without any galling. The alloy steel feels solid, and the black oxide coating gives them a uniform, no-nonsense look.
