# 955566 Hexagon Screw | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta hexagon screw with a 1/2 UNC thread, listed as 1/2 UNC x 64, weighing 0.074 kg and covering 189 applications across the MD, TMD, D, TD, AQ and AQD series. The imperial thread is what decides the order - a metric screw will not run into this tapping, and 955539 in the same run is the 3/8 UNC size.

## 🚤 Compatibility

-   **Engine Family:** MD, TMD, D, TD, AQ, AQD, TAD, TAMD, TWD, BB, TID, THD, THAMD, B, DH, MB

Full model list at the end of this description.

## ⚙️ Key Features

-   1/2 UNC thread, listed as 1/2 UNC x 64
-   0.074 kg
-   189 applications across six engine series
-   L=64mm (Volvo assembly listing)

## 🔌 Function

Bolts two components together through an imperial-threaded tapping, clamping the joint under a plain hexagon head.

## ⚠️ Common Signs of Failure

-   Screw found loose or backed out at service

-   Thread stripped, often from a metric screw having been forced in
-   Screw stretched or snapped at the shank

## 🛠️ Service Notes

-   Check the thread size against 955539, the 3/8 UNC screw here - the two are not interchangeable
-   Run a tap or chase the tapping out if a wrong-thread screw has been in it
