براغي رأس سداسي 1-1/8-7 × 3 بوصة | صناعة أمريكية | فولاذ درجة 8 مطلي بالزنك الأصفر (30 / عبوة)

The threads on these Grade 8 cap screws are perfectly clean and cut without any burrs, which made installation smooth. The yellow zinc finish looks great, too, and for thirty of these heavy-duty fasteners, the price was a steal.

These bolts held up through a full week of constant vibration on our press without backing off a quarter turn. The yellow zinc coating looks factory-fresh even after being drenched in cutting fluid, and the threads stayed clean out of the pack.

I needed some heavy-duty fasteners for a trailer hitch repair, and these Grade 8 bolts fit perfectly without any stripping. The yellow zinc coating seems tough, and the hex head made it easy to torque down with a socket. Just wish they came in a slightly larger quantity for the price.
