FAQ
Frequently Asked Questions
Not exactly. A jam nut is typically a thinner nut tightened against a standard nut to lock it. A locknut is a single nut with an integrated locking feature (like a nylon ring). However, in some contexts, 'jam nut' is used loosely to mean locknut.
It depends on the type. Nylon-insert locknuts are generally not recommended for reuse as the nylon wears. All-metal deformed thread locknuts can sometimes be reused a limited number of times, but manufacturer specifications should always be followed for critical applications.
They are vital in aerospace, automotive, heavy machinery, and any industry where mechanical failure due to vibration could be catastrophic.
Usually not. Most locknuts are installed with standard wrenches or sockets. However, proper torque specification is often more critical than with a standard nut.
