براغي رأس مقبس 5/8-18 × 2-1/2 بوصة | محرك سداسي | صنع في الولايات المتحدة | فولاذ سبائكي مع أكسيد أسود حراري (175/عبوة)

I needed some heavy-duty screws for a jig I’m building, and these 5/8-18 x 2-1/2" socket cap screws feel solid as a rock under the wrench. The hex drive seated perfectly without stripping, and the black oxide finish looks clean and professional.

The black oxide finish on these screws has held up perfectly after a week of clamping and unclamping on my jig table, no rust or wear marks anywhere. The hex socket drive seated cleanly on every single one of the 175 pieces, which is rare for bulk hardware.

Installing these on a milling fixture and the hex socket drive made torquing them down a breeze. The black oxide finish seems durable and the threads are clean; definitely a solid upgrade from the generic ones I'd been using.
