## ⚙️ Key Features

-   Marine propulsion lock tab
-   0.0023 kg
-   Listed for 33 applications across the D series and IPS drives

## 🔌 Function

Locks a nut or bolt mechanically by having a tab bent up against a flat, so the fastener cannot rotate loose under vibration.

## ⚠️ Common Signs of Failure

-   Fastener found loose despite having been locked
-   Tab already bent flat or broken off
-   Tab cracked at the fold from being bent more than once
-   Washer face distorted or dished
-   Metal debris from a broken tab found in the housing

## 🛠️ Service Notes

-   Lock tabs are single-use - a tab that has been bent once is work-hardened and will crack, so fit a new one every time
-   Lock nut 3819151 in the same group is the heavy 1.024 kg nut this class of tab is used with
