Crown Lock Nut CR060080-001 – CR60080-001

A lock nut cataloged for Crown equipment, built to resist loosening under the vibration that backs a standard nut off its bolt. It carries a locking element, typically a deformed thread or a nylon insert, that grips the bolt threads and holds tension without a separate lock washer or thread-locking compound.

That locking feature wears with repeated installation and removal, since each reuse reduces the friction it can generate, so lock nuts are generally treated as one-time-use at joints that matter. Match the thread diameter and pitch to the bolt it threads onto, since the nut has to engage the same thread to lock.
