22329289 Flange Screw | Genuine Volvo Penta Part

🔧 Product Description

A genuine flange-head screw used in the electrical and control-component mounting arrangement of selected Volvo Penta TAD550/TAD551 and TAD750-series generator engines. Its integrated flange, thread, length and strength specification provide the required clamp load without a separate washer.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD550GE
• Volvo Penta TAD551GE
• Volvo Penta TAD750GE
• Volvo Penta TAD751GE

• Engine Family: TAD

⚙️ Key Features

• Genuine Volvo Penta flange screw
• Catalogued in TAD5/TAD7 generator electrical assemblies
• Integrated flange spreads clamp load
• Correct thread, length and strength class
• Supports secure mounting under engine vibration
• Do not substitute by appearance alone; verify dimensions and grade
• 2 used per assembly

🔌 Function

Clamps the specified bracket or electrical component to the engine while maintaining alignment and vibration resistance.

⚠️ Common Signs of Failure

• Rounded head or damaged flange
• Stretched, corroded or galled threads
• Repeated loosening or fretting
• Incorrect length bottoming before clamp load is reached
• Wrong strength grade previously installed

🛠️ Service Notes

• The integral flange spreads the load and forms the bearing face, so do not add a separate washer unless the workshop manual for your engine specifically calls for one
• Clean the threads and the seating face before fitting — grit, paint or old sealant under the flange gives a false torque reading and the joint will slacken off in service
• Where the flange is serrated it must bear directly on clean metal to grip; discard any screw with a deformed flange or damaged serrations rather than reusing it
• Tighten to the torque and sequence given in the workshop manual for your engine, and treat the screw as single-use where the manual specifies an angle-tightened or stretch fastener
• Check the thread in the receiving component at the same time; a pulled or corroded thread will not hold a new screw however carefully it is torqued
