مسامير زنبركية 5/16 × 1-1/8 بوصة | مشقوقة | فولاذ مطلي بالزنك (500 / عبوة)

Installed these on a hinge rebuild for an old trailer and they drove in smoothly without binding. The zinc plating on all 500 pins is consistent, no rough edges.

The 500-count pack gives me plenty of spares for my shop projects, and the zinc plating resists rust well. These pins slide easily into my fixtures and hold firm even on a vibrating mower deck.

The zinc plating looks clean and even across all 500 pins, and the 5/16" diameter holds tight in my jig without any wobble. I've used them for aligning two steel plates under constant vibration and they haven't budged after a week of hard use.
