A Jam Nut is a thin, low-profile nut designed for applications where space is limited or where an additional nut is required to secure a threaded connection. It is generally thinner than a standard hex nut and is often used together with a standard nut to create a locking arrangement.
Jam Nuts can be tightened against another nut to help prevent unwanted movement caused by vibration or continuous operation. They are also useful in applications where a standard-height nut may not fit or where controlled positioning of a component is required.
How Jam Nuts Work
A Jam Nut is commonly installed against a standard nut on the same threaded bolt or stud. Once tightened against the primary nut, it creates a clamping action between the two nuts, helping maintain the position of the threaded assembly.
Jam Nuts can also be used where fastening directly against a delicate or relatively soft material may cause damage. In certain mechanical applications, they can provide adjustable positioning while allowing a component to move or rotate as required.
