0.016 kg - Supersedes 946435 - 366 applications - Covers the D, IPS, V, DPH, TSK and DPI ranges - 2 used per assembly ## 🔌 Function Holds a threaded joint tight against vibration, resisting the tendency of a plain nut to work loose in service. ## ⚠️ Common Signs of Failure - Nut found slack or backed off despite being tightened - The nut spinning down the thread with no resistance at all - Flats rounded or the nut deformed out of shape - Thread stripped or picked up on removal - Rust or scale binding the nut on the stud ## 🛠️ Service Notes - A lock nut that runs freely down the thread has lost its locking action and must not be refitted, even if it looks sound - Check the stud or bolt thread before running a new nut on - a damaged male thread will spoil the new nut too ## 🔄 Supersession & Cross Reference ### OEM Supersession Chain - 984456 → Supersedes 946435 ### OEM / Related Numbers - 946435 earlier number superseded by this part ## 📦 Condition -
