براغي رأس سداسي 1-1/4-12 × 5 بوصة | صناعة أمريكية | فولاذ درجة 8 زنك أصفر (15/عبوة)

Threads were clean and uniform on all fifteen, no burs or junk in the zinc coating that would snag a wrench. Took a beating on a vibration-heavy jig without backing out even a hair, which is exactly what I needed from a Grade 8 fastener.

Had to replace some fasteners on a heavy-duty trailer hitch, and these Grade 8 cap screws threaded in smoothly with a socket—no binding at all. The yellow zinc finish looks solid and the hex head held torque perfectly.

Installed these on a skid steer attachment, and the Grade 8 steel held up way better than the cheap bolts I used before. Threads cut smooth and the hex head grabbed my socket perfectly.
