1-1/4-7 X 2-3/4" براغي رأس سداسي | صناعة أمريكية | فولاذ درجة 8 أصفر زنك (25/عبوة)

These threads took a serious load without a hint of stripping or flexing, and the hex head seating in a socket is nice and deep for a wrench. Grade 8 quality is apparent the second you handle them, these are the real deal for equipment work.

The yellow zinc finish is holding up way better than the old hardware I pulled off, and the grade 8 steel means I’m not second-guessing the torque on these. Threads cut clean into the frame without any binding.

Had to replace some bolts on a large press at work and these Grade 8 screws torqued down perfectly without stripping. The yellow zinc coating is holding up well in the oily environment.
