براغي رأس سداسي 1-1/8-7 × 6" | صناعة أمريكية | درجة 8 فولاذ أصفر زنك (15/عبوة)

Bought these for a heavy-duty trailer hitch repair, and the yellow zinc coating looks like it’ll hold up well against road salt. The hex head gave my socket a solid grip without slipping.

I've been using these on a heavy-duty press rebuild and the Grade 8 steel is noticeably tougher than the Grade 5s I had before. The hex head fit my socket perfectly and the yellow zinc coating has held up well without any rust so far.

Threaded these onto a large industrial press frame, and the Grade 8 steel held up perfectly under full torque—no stripping or galling. The yellow zinc finish looks clean and resists rust too.
