# 984259 Six Point Socket Screw | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta six point socket screw, 40 mm long, weighing 0.027 kg and listed for 17 applications across DPH and D drives. Screw 984258 is also 40 mm long, so length alone will not separate the two: that one additionally covers TSK units, while this one is listed only against DPH and D. Match the fitment as well as the length before ordering.

## 🔌 Function

Clamps two components together, its six point socket head giving full tool engagement in a recessed position.

## ⚠️ Common Signs of Failure

-   Socket rounded out by a worn or undersized key
-   Debris packed into the socket so the tool will not seat fully
-   Thread stripped or picked up on withdrawal
-   Corrosion seizing the screw into the casting

## 🛠️ Service Notes

-   Two 40 mm screws are listed in this run, so check the application listing as well as the length
-   Clean the socket out fully and seat the key before applying load, since a partly engaged tool will round the head
