993474 Hex Socket Screw | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta hexagon socket screw weighing 0.018 kg and listed for 88 applications on D series engines. Socket screw 993604 covers the same 88 D series applications at 0.014 kg, so the two are close relatives fitted around the same engines - only 4 grams and the part number separate them, and weight is not something you can check on the bench.

🚤 Compatibility

• Engine Family: D
• HP Range: 110-480 HP

Full model list at the end of this description.
