3/4"-16 Right Hand Fine Thread Steel Silver Zinc Plated Thin Nyloc Jam Nuts

In offroad racing, it's common to have an issue with traditional jam nuts loosening up from vibration. Nylocs are a great solution for this problem. However you would NOT use a Nyloc nut on a heim joint, threaded upside down, and used as a jam nut against a bung.

A Nyloc nut is designed to be threaded onto a bolt with the Nylon facing away from the bolt. If you're looking for jam nuts for a heim joint, then you would use standard jam nuts, not Nylocs. If you're still having issues with standard jam nuts loosening up, then you could use a bit of blue Loctite.

This six point steel hex nut has fine thread and silver Zinc plating.
