991607 Flange Screw | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta flange screw marked M10X50, weighing 0.041 kg and listed for 35 applications across the IPS and D series. Order it on the marked thread size: the neighbouring flange screw 991608 is marked M12x50 yet carries a lower published weight of 0.023 kg, so the published figures do not rank with the thread sizes and cannot be used to tell the two apart.

🚤 Compatibility

• Engine Family: IPS, D

⚙️ Key Features

• Marked M10X50
• 0.041 kg
• 35 applications across the IPS and D series
• Order by the marked thread size, not by weight

🔌 Function

Clamps a joint with an integral flanged head that spreads the load over the mating face without a separate washer.

🛠️ Service Notes

• Check the thread marking on the old screw before ordering — the M12x50 screw 991608 sits next to this one in the range and the published weights run the wrong way round to be any help
