Ive purchased this item in the past. I'm doing a lawn tractor upgrade on my deck. I'm using this nylon nuts to hold my deck wheels in place, so they don't get loose and fly off.

Great Nuts!

Would Recommend

I try to use nylon insert nuts whenever I can. Crush washers are basically useless. The threads were perfect, the finish was bright. Nylon inserts prevent vibration from loosening the hardware.

These lock nuts have never failed me. I use these on all my finishing work. I don’t have to fool with lock washes with these nuts. Once tight, always tight
