براغي رأس سداسي 3/4-10 × 1" | صناعة أمريكية | فولاذ درجة 8 مع زنك أصفر | كامل الخيوط (25 / عبوة)

I’ve been using these to bolt down a heavy-duty conveyor frame at the shop, and the yellow zinc finish has held up way better than the standard black oxide ones I used before. The grade 8 steel threads cut cleanly into the nut without any binding, which is a huge relief when you’re working in tight

The hex head on these is deep enough that my socket driver grips firmly without slipping. The yellow zinc coating looks consistent across all 25 screws in the pack.

I needed some heavy-duty fasteners for a jig I was building, and these Grade 8 steel screws handle the torque without stripping. The yellow zinc coating looks good and should resist rust well.
