براغي رأس سداسية مقاس 7/8-9 × 3-1/2 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (50/عبوة)

The partially threaded design made these cap screws easy to start by hand before tightening with a socket, and the yellow zinc finish looks clean and industrial. I used them to secure a motor mount and they held firm without any stripping.

Had to replace some worn hardware on a piece of shop equipment, and these cap screws threaded in smoothly with no binding. The yellow zinc coating seems thicker than the old ones I pulled out.

I was a little worried about the partial threads, but these grade 5 bolts tightened up perfectly on my skid loader’s bucket hitch. The yellow zinc coating looks heavy-duty and should resist rust in our damp shop.
