Jam Nuts
Jam nuts are thin, low-profile nuts used as secondary locking devices or in applications with limited thread engagement. American Bolt Corporation supplies jam nuts for industrial, mechanical, and maintenance applications where a secondary nut or space-constrained fastening is required.
Jam nuts are often used in conjunction with standard hex nuts or in assemblies where clearance is limited.
What Is a Jam Nut?
A jam nut is a thin hex nut with the same thread size as a standard nut but reduced thickness. When used as a locking nut in combination with a primary nut, the jam nut is tightened against the primary nut to help “lock” it in place by creating opposing forces. Jam nuts are also used where:
- Full-thread engagement is not available
- Clearance is limited
- A low-profile nut is needed
- Backing or secondary locking is required
