Top Quality
Replaced some galvanized hardware that had rusted so badly I had to split the nuts and bolts with a cutoff wheel in my moto-tool. These nuts will never rust.

Nuts bind after threading in about 3/4”
Dislike. Binds after threading in on bolt about 3/4” in. Regular 5/16-18 SS nut threads on bolt perfectly so something is wrong with these nuts. Tried this three times and had to break the bolt off because could not get the bound nut off the bolt. Now I have 50 nuts that are useless and my work is delayed.

Not matching size
Does not fit #10-32 SS 316 screws. Starts threading fine intil hits the nylon part, then goes few turns and stops hard.Have to other other nuts.
