# 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
