A jam nut is a thin hex nut typically used in combination with another nut to prevent loosening under vibration or torque.
Its low-profile design makes it ideal where space is limited or where a standard nut’s height is not required.
When tightened against a standard nut, the jam nut creates friction on the bolt threads, locking both nuts in position.
This model is made from high-strength stainless steel, providing excellent corrosion resistance for both indoor and outdoor use.
Jam nuts are widely used in machinery, automotive assemblies, agricultural equipment, and industrial maintenance, where reliability and security are essential.
