🔌 Function

Clamps a component or terminal down on the engine, holding it in position and, where a terminal is involved, maintaining the electrical contact pressure.

⚠️ Common Signs of Failure

• Component or terminal loose in service
• Head drive worn so a tool will not grip
• Thread stripped or corroded
• Screw seized and snapping on removal
• Intermittent operation where the screw holds an electrical contact

🛠️ Service Notes

• The three superseded numbers were previously a circuit breaker assembly, a screw and a switch - if you are working from an old list, confirm the illustration rather than assuming a screw is what you need
• Where the screw clamps an electrical terminal, clean the contact faces and tighten to a firm, even load
