⚙️ Key Features

• 0.045 kg
• 25 D-series applications
• Integral flange face

🔌 Function

Locks a stud or bolt with an integral flange that spreads the clamping load over the joint face, removing the need for a separate washer.

⚠️ Common Signs of Failure

• Nut backing off and the joint working loose
• Serrations or flange face flattened
• Thread stripped or pulled
• Corrosion locking the nut to the stud so it shears on removal

🛠️ Service Notes

• Renew rather than reuse where the flange face has picked up or the thread has galled
• Clean the joint face before fitting - a flange nut only holds torque against a flat, clean surface

📦 Condition

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