براغي رأس سداسي ثقيلة 5/8-11 × 3-1/2 بوصة | صناعة أمريكية | فولاذ A307 درجة B مطلي بالزنك | ملولبة جزئيًا (100/عبوة)

I needed some heavy-duty bolts for a repair stand I'm building, and these A307 Grade B steel ones feel solid with that zinc coating looking clean. The 100-count box is a good value for the money, no complaints.

The zinc plating on these bolts looks flawless out of the box, no chips or dull spots anywhere across the hundred pieces. I used them to mount a heavy equipment frame and the 5/8-11 threads bit in clean without any galling, so they've earned a spot in my regular fastener rotation.

The zinc coating on these bolts looks good and the threads cut cleanly into the steel I was mounting. Used them to fasten a heavy bracket to a trailer frame and they seated perfectly with no wobble.
