Jam Nuts
What is a Jam Nut and how are they used
A Jam nut is a low profile nut designed to be tightened against the mating material and then having a finished or heavy hex nut tightened against the jam nut to keep it from loosening.
- When fastening soft or brittle materials it is suggested to use a jam and hex nut assembly to keep the materials in place without damaging them from pressure.
- Jam nuts are also used in applications where a component is needed to move freely on the bolt of stud.
- In areas where space is limited, a jam nut can be used instead of a standard hex nut but is recommended to use thread locker if vibration is a concern.
- A double nut assembly can also be used if there is concern of stripping the threads of the bolt or stud.
