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.

⚠️ 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
