# 21344750 Hexagon Screw | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta hexagon-head screw used at a specified engine assembly position. The fastener is selected for exact diameter, pitch, grip length, strength class and flange/washer arrangement; it must be matched against the illustrated parts catalogue and not replaced by a visually similar general fastener.

## ⚙️ Key Features

-   Hexagon-head screw for a specified engine assembly position
-   0.272 kg
-   Supersedes 1543316, catalogued earlier simply as a screw
-   Listed for 27 applications across the D, TWD and TAD ranges

## 🔌 Function

Clamps the joint at its assigned engine position, providing the specified diameter, grip length and strength class for that fastening.

## ⚠️ Common Signs of Failure

-   Joint weeping or a component moving where it should be solid

-   Mating faces found fretted where clamp load has been lost

## 🛠️ Service Notes
