HOLO-KROME 32196 7/16-14 X 1/2" براغي ذات رأس كوبي ومقبس سداسي | فولاذ سبائكي أكسيد أسود حراري (100 / عبوة)

Had to replace some worn-out cap screws on a jig at work and these went in perfectly smooth, the hex socket drive seats without any wobble. The 3/8-16 threads are clean and the thermal black oxide coating looks consistent across all fifty pieces. Solid buy for precision assemblies, I'd grab another

The black oxide finish on these screws provides a nice, professional look for my jig build, and the hex drive makes installation a breeze. I used them to secure a heavy-duty fixture and they held perfectly without stripping. Great feel and quality for the price.

I needed a batch of strong cap screws for a custom jig build, and these 3/8-16 x 3-1/2" units held tight without any stripping. The black oxide finish gave them a clean, professional look, and the hex socket drove smoothly even in tight spaces.
