17602 Hexagon Nut | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta hexagon nut is a structural mounting or fastening component used in the legacy engine or driveline fastening point. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it provides the specified threaded clamping force for the matched stud or bolt. Selection must be confirmed by OEM part number 17602, the exact engine/product model, serial number and installed configuration.

🚤 Compatibility

• Engine Family: TAMD, AD, D, TWD, TID, TMD, TD, MS, HS, TAD, KAMD, MD, KAD
• HP Range: 13-480 HP

🔌 Function

Provides the specified threaded clamping force for the matched stud or bolt. Inspect threads and contact faces, replace one-time locking hardware where specified and tighten to the Volvo Penta torque and sequence for the exact assembly.

⚠️ Common Signs of Failure

• Nut backing off under vibration and losing clamping load
• Thread damage, galling or seizing making removal difficult
• Rounded or deformed hexagon flats that no longer accept a socket
• Corrosion or pitting in the marine environment
• Joint leakage or movement traced to loss of fastener torque

🛠️ Service Notes

• Check the stud or bolt thread is clean and undamaged and run the nut down by hand first; grit on the thread gives a false torque reading
• Tighten to the torque in the workshop manual for your engine, following the specified sequence on multi-fastener joints and working round in stages so the load comes up evenly
• Renew self-locking and all-metal locking nuts rather than reusing them — once the locking feature has been through a cycle it no longer holds reliably
• Fit the washer, tab or locking arrangement that belongs with that joint; a locking device that was bent or crimped in service should be replaced, not straightened and reused
• Marine-grade anti-seize on stainless threads reduces galling and makes later removal possible, but keep it off threads that must take a locking compound
