🔌 Function

Provides a fixed threaded post that a component is located on and clamped to by a nut, so the joint can be parted repeatedly without wearing the thread in the casting.

⚠️ Common Signs of Failure

• Nut spinning without torquing up
• Stud stretched or necked down
• Stud pulling out of the casting
• Thread corroded so the nut seizes on removal
• Stud snapped off flush with the face

🛠️ Service Notes
