صواميل قفل مقاس 1/2"-20 | فولاذ مطلي بالزنك (200/عبوة)

The zinc plating looks even and clean across all 200 pieces, no rough edges or flakes that sometimes come with cheaper hardware. I've used about half of them on a trailer build so far and they thread onto my bolts smoothly every time.

The hex head made it easy to grip with a wrench, and the zinc plating on all 200 pieces looked consistent with no defects. They threaded smoothly onto my 1/2"-20 studs without any binding.

I needed a solid batch for a few projects and these zinc plated jam nuts threaded onto my 1/2"-20 bolts without any cross-threading issues. The hex head made it easy to cinch them down firm with a standard wrench, and the 200 count box is way more than I'll need but the price was right.
