🔌 Function

Clamps two components together across the joint, tightened by a spanner or socket on its hexagon head.

⚠️ Common Signs of Failure

• Screw found loose or backed out
• Shank stretched, with a visible waist
• Head corners rounded so a spanner slips

🛠️ Service Notes

• Check the length against the screw you removed - a 60 mm screw in a shallower hole will bottom out before it clamps
• Renew rather than reuse a screw that shows any waisting
