براغي رأس سداسي 1/4-20 × 1-3/8 بوصة | فولاذ درجة 8 زنك أصفر | ملولبة جزئياً (1600/عبوة)

The hex head on these grade 8 screws really grabs a wrench firmly without slipping, and the yellow zinc coating looks uniform across all 1600 pieces. I used them to rebuild a small farm trailer hitch and every bolt seated cleanly in the pre-tapped holes.

Finally got around to sorting through the whole box and every single one of the 1600 has the threads clean and the hex heads crisp. The partial threading on these grade 8s is exactly what I needed for a tight clamping setup without any play.

Used a full box of these on a trailer rebuild. The zinc coating is even and the threads run smooth all the way down. Good value for the quantity and strength.
