1/2-13 × 1-1/8" براغي رأس سداسي | فولاذ درجة 8 مطلي بالزنك الأصفر | ملولبة بالكامل (400 / عبوة)

Used these on a heavy equipment repair and the Grade 8 steel held up perfectly under the torque. The fully threaded design made installation quick, and the yellow zinc coating looks consistent across all 400 pieces.

The yellow zinc finish is even and consistent across all 400 pieces, and the threads are clean with no burrs. I used them to reassemble a jig on my mill table and every one seated perfectly with a socket. These are exactly what you want for a production run.

Took a chance on these for a big equipment assembly job and the yellow zinc coating is flawless across all 400 pieces. The hex heads grabbed cleanly with my socket wrench, no stripping or soft spots, and the fully threaded length made alignment easy.
