# 990034 Hex Socket Screw | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta hexagon socket screw from the marine propulsion group, weighing 0.009 kg and listed for a single SX-drive application.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta SX-MTD3

-   **Engine Family:** SX

## ⚙️ Key Features

-   0.009 kg
-   One SX-drive application
-   Internal hexagon drive
-   Marine propulsion group
-   2 used per assembly

## 🔌 Function

Clamps two components together with an internal hexagon drive, for positions where there is no room to swing a spanner on a hexagon head.

## ⚠️ Common Signs of Failure

-   Socket rounded out so a key will no longer bite
-   Head corroded and packed with salt
-   Thread seized in its tapping
-   Screw backing off and the joint weeping

## 🛠️ Service Notes

-   Hexagon socket screw 990413 is listed at the same 0.009 kg but against 45 applications across the D, TAD, TWD and TADH ranges - the published weight does not separate the two, so order by part number
-   Clear the socket completely before applying a key; a partly seated key is what rounds these out
