صواميل سداسية 5/16-18 بوصة | فولاذ مطلي بالزنك (150 / عبوة)

I needed a solid supply of 5/16"-18 nuts for a large project, and these 150-count packs are perfect. The steel feels sturdy with a consistent zinc coating that matches my bolts well. No stripping issues so far.

The zinc plating on these nuts is smooth and even, no flaking or rough edges right out of the package. I've used about forty so far and every single one threaded cleanly onto my 5/16" bolts without any binding, which is more than I can say for other bulk packs I've tried.

Threaded them onto some 5/16" bolts for a trailer hitch project and every one spun on clean right out of the package. The zinc coating feels solid and uniform, no flaking or rough edges. A full 150-count box means I'll have plenty left for future jobs.
