🔌 Function

Threads onto a stud or bolt and resists loosening under vibration, holding its clamping force where a plain nut would back off.

⚠️ Common Signs of Failure

• Nut spinning on freely, showing the locking action is spent
• Joint working loose and rattling
• Corners rounded so a spanner slips
• Thread stripped or picked up on the stud
• Corrosion seizing the nut to the stud

🛠️ Service Notes

• Lock nuts are generally renewed rather than reused once they have been slackened, since the locking action weakens each time
• If a lock nut runs down the thread by hand, it is no longer doing its job

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
