Great nut

I purchased this to replace the nut off a bolt on a wagon I use for transportation. This nut performed to the utmost level only outdone by its appearance. The anti corrosion treatment is going to be a wonderful investment for the future. It's plastic insert will assist with the vibratory factors. The grip is solid as possible. The threads were a perfect fit ..

Worked for me.

Would Recommend

Exactly what I needed. Sometimes metric hardware is hard to find, but Lowes had a good selection.

A scooter that VA gave to me because I am 100% disabled and unable to walk well, had 2 8Mx125x8"bolts with nuts that would not stay tightened. I bought Hillman lock nuts and installed them above the nuts that came with the scooter and now everything is secure.
