⚙️ Key Features

• 171 mm long
• 0.088 kg
• 64 applications across six series
• L=171mm (Volvo assembly listing)
• Quantity varies by assembly, most commonly one

🔌 Function

Clamps a deep bolted joint to its set torque, the long shank carrying the load through the assembly.

⚠️ Common Signs of Failure

• Joint loosening or moving under load
• Thread stretched or stripped over the long grip
• Screw bent, or the shank corroded along its length
• Head rounded off by a slipping spanner

🛠️ Service Notes

• Check the shank for straightness and corrosion before reusing anything of this length, as a long screw that has been stretched will not hold torque
• Clean the tapped hole out fully before fitting, since debris at the bottom of a deep hole gives a false torque reading

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
