## 🔧 Product Description

## 🔌 Function

Secures a stud or bolt at a joint, holding the clamp load on the assembly against the vibration that would otherwise slacken it.

## ⚠️ Common Signs of Failure

-   Nuts found slack, backed off or missing, particularly on mountings and joints that see vibration
-   A joint working, knocking or leaking because the fastener has lost its clamping load
-   Corroded or seized nuts, or ones that will not undo without rounding the flats
-   A locking nut that spins freely down its thread, showing the locking feature is spent

## 🛠️ Service Notes

-   Check the stud or bolt thread is clean and undamaged and run the nut down by hand first; grit on the thread gives a false torque reading
-   Tighten to the torque in the workshop manual for your engine, following the specified sequence on multi-fastener joints and working round in stages so the load comes up evenly
-   Renew self-locking and all-metal locking nuts rather than reusing them — once the locking feature has been through a cycle it no longer holds reliably
-   Fit the washer, tab or locking arrangement that belongs with that joint; a locking device that was bent or crimped in service should be replaced, not straightened and reused
-   Marine-grade anti-seize on stainless threads reduces galling and makes later removal possible, but keep it off threads that must take a locking compound
