🔧 Product Description

Genuine Volvo Penta spring nut weighing 0.002 kg and listed for 70 applications on D series engines. It supersedes part number 191391. A spring nut clips over an edge or into a panel to give a captive thread where there is no room for a conventional nut and spanner behind the joint.

⚙️ Key Features

• 0.002 kg
• Listed for 70 applications
• Fits D series engines
• Supersedes 191391

🔌 Function

Clips onto the panel to provide a captive threaded anchor, holding itself in place so a screw can be driven from one side only.

⚠️ Common Signs of Failure

• Nut spinning in its seat so the screw will not tighten
• Clip sprung open and falling off the panel edge
• Thread stripped or the screw pulling straight through
• Rust locking the screw and nut together

🛠️ Service Notes

• These are cheap and easily distorted on removal - fit new ones rather than reusing clips that have been prised off
• Check the panel edge or slot for splits, as a damaged seat will let the new nut spin as well
