🔌 Function

Screws into a casting to leave a permanent threaded pillar, so the joint can be made and broken on a nut rather than on the casting's own thread.

⚠️ Common Signs of Failure

• Stud winding out of the casting with the nut still on it
• Thread necked or stretched from overtightening
• Corrosion where the stud passes out of the casting
• Nut no longer able to hold torque

🛠️ Service Notes

• Check the tapped hole is clean and undamaged before fitting, and set the stud to the specified depth
• If the old stud pulled its thread, deal with the casting before fitting a new one
