## 🔧 Product Description

This genuine Volvo Penta six-point socket screw is used in the following application: Volvo Penta electrical cable / fuse mounting assemblies whose schematic specifies 22390501. Secures the specified electrical bracket, cable support, fuse component or adjoining hardware with the designed clamp load.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta HPCU-A
-   Volvo Penta TB66-150-A

-   **Engine Family:** HPCU, TB

## ⚙️ Key Features

-   Genuine Volvo Penta six-point socket-head fastener
-   Officially catalogued in the cables-and-fuses system group
-   Original thread, length, strength class and head geometry for the assigned mounting point
-   Positive internal drive supports controlled installation torque
-   Fastener only; washer, nut, clamp or mounted component are separate unless shown otherwise
-   Do not replace with a visually similar hardware-store screw without verifying every specification

## 🔌 Function

Secures the specified electrical bracket, cable support, fuse component or adjoining hardware with the designed clamp load.

## ⚠️ Common Signs of Failure

-   Rounded or damaged internal drive
-   Stretched, corroded or galled threads
-   Incorrect length or strength grade installed
-   Loose electrical bracket or cable support
-   Fretting around the mounting point
-   Fastener damaged during removal from a torque-controlled joint

## 🛠️ Service Notes

-   Use a socket or key that engages the head fully and squarely; a worn or part-inserted tool rounds the flats and turns a simple job into a drilling job
-   Clean the threads and the seating face, and check the screw for stretched or corroded threads and a damaged head — renew rather than reuse anything doubtful
-   Where the original was fitted with a thread-locking or sealing compound, or with a washer or seal, fit the same again; many of these screws seal a fuel or oil passage as well as clamping it
-   Tighten to the figure and sequence given in the workshop manual for your engine, working evenly across a multi-screw joint rather than pulling one screw fully down at a time
-   A smear of a suitable marine anti-seize on exposed threads makes the next removal far easier, but keep it off threads meant to be locked or sealed
