براغي رأس أسطوانية بمقبس سداسي 5/8-11 × 4-1/2 بوصة | محرك مقبس سداسي | صناعة أمريكية | فولاد سبائكي أسود حراري مؤكسد (125 / عبوة)

I needed some heavy-duty bolts for a jig I’m building, and these 4-1/2" socket cap screws fit the bill perfectly. The alloy steel feels solid, and the hex socket drive engaged smoothly with my wrench.

The black oxide finish on these 5/8-11 socket cap screws is really uniform and smooth, no burrs at all. I used them to secure a heavy jig on my mill table and they torqued down perfectly without stripping. Solid buy for the price per pack.

The threads on these screws are clean and sharp, and the black oxide finish looks great. Used a few on a heavy jig I'm building, and the hex socket drove in tight without any issues. Exactly what I needed for a strong hold.
