براغي رأس سداسي #7/8-14 × 6 بوصة | فولاذ درجة 5 بزنك أصفر | ملولبة جزئيًا (15/عبوة)

Had to tighten a large flange on an old press and these threaded in smoothly without any binding. The yellow zinc coating looks consistent across all fifteen pieces, so they should hold up fine.

I finally ordered these for a heavy-duty machine base I’m building. The grade 5 steel feels solid under the wrench, and the yellow zinc coating looks like it’ll hold up well.

The partially threaded design made driving these into a welded bracket much easier than fully threaded bolts would have. The zinc coating looks clean and the hex heads fit a standard socket perfectly. A solid value for the price.
