صواميل قفل 7/16-20 | فولاذ مجلفن (1000 / عبوة)

For a full box of a thousand, the zinc plating is surprisingly even across every single nut I've checked so far, and they thread cleanly onto 7/16" bolts without any binding. I've been through about two hundred of them on a current stud job, and not one has come up defective or rough.

These hex head jam nuts threaded onto my 7/16"-20 bolts without any binding, and the zinc plating looks clean and consistent across all 1000 pieces. I used them for a full trailer rebuild and didn't have a single reject.

Zinc coating on these jam nuts seems to hold up better than others I've used, no rust after a few months in a slightly damp shop. The hex heads grip a wrench perfectly, and having 1000 in a package is way more than enough for most projects.
