براغي غطاء رأس سداسي 1 بوصة-8 × 4 بوصات | فولاذ درجة 5 مطلي بالزنك الأصفر | خيط جزئي (35 / عبوة)

The partially threaded shaft gives me plenty of grip for clamping down thick steel plates, and the hex head fits a socket perfectly without stripping. I used these on a press rebuild and all 35 went in smoothly, no binding or bad threads in the batch.

The yellow zinc coating on these Grade 5 bolts is holding up great so far—no rust after a week of outdoor use on my trailer hitch setup. The partially threaded design made alignment a lot easier than fully threaded ones I've wrestled with before.

I used these for some heavy machinery repairs, and the Grade 5 steel yellow zinc held up perfectly under torque. The partially threaded design made installation quick and the hex head fit my socket like a glove. Exactly what I needed for the job.
