Locking Nut - 3/8" UNF.

Imperial 3/8" UNF locking nut, supplied individually. A locking nut is specified in place of a plain nut wherever vibration would otherwise allow a joint to work loose over time.

The locking feature is at its most effective on first use. A nut that spins freely down its thread has lost it and should be replaced rather than refitted.

Frequently asked questions

What is the NV606041L locking nut?
The NV606041L is a 3/8 UNF locking nut, an imperial thread fastener used where a plain nut could vibrate loose. Locking nuts hold clamping force through a friction or deformation feature rather than relying on thread tension alone.
Can a locking nut be reused?
Locking nuts are typically treated as single use. The locking feature loses effectiveness each time the nut is run on and off, so once it spins on freely by hand it has stopped doing its job. Fitting a fresh one is the standard approach on any joint that matters.
How do I confirm this is the right nut for my application?
Match the part number NV606041L and the 3/8 UNF thread against the fastener you're replacing. UNF is an imperial thread form, and it won't interchange with a metric nut even where the outside diameter looks close. Thread pitch is what decides fitment here.
