براغي رأس سداسي | 1/4-28 × 5/8" | فولاذ درجة 8 أصفر زنك | خيط كامل (3000 / عبوة)

If you're doing a big build, buying these by the box is the way to go. The 1/4-28 threads are clean and started into my die nuts without any fighting, and the yellow zinc finish looks consistent across all 3000 pieces. Took a while to receive them, but the grade 8 strength is exactly what I needed f

The threads on these fully threaded screws cut cleanly into steel, and the Grade 8 strength gives me confidence they won’t strip under heavy torque. A solid choice for machine assembly.

The hex heads on these screws fit my socket perfectly, and the yellow zinc finish looks clean and uniform across the entire box. I used about 200 of them for a tractor linkage repair and the threads cut smoothly with no galling.
