🔌 Function

Provides a fixed threaded post so a component can be pulled down squarely onto its gasket by a nut.

⚠️ Common Signs of Failure

  • Nut will not torque up and the stud turns in its thread
  • Thread stripped, stretched or necked down
  • Stud corroded thin or seized solid in the casting
  • Leak at the joint the stud clamps, from uneven pull-down

🛠️ Service Notes

  • Renew studs as a set on a joint rather than one at a time, so the clamping load stays even
  • Clean the casting thread and check the stud stands to the right height before fitting the nut

📦 Condition

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