⚙️ Key Features

• 0.05 kg
• 20 applications across the TAD series
• Supersedes 20460205

🔌 Function

Clamps two components together, the tension held in its shank keeping the joint tight against vibration.

⚠️ Common Signs of Failure

• Joint working loose or weeping at the face
• Head rounded off or the drive faces chewed
• Thread stripped or galled on removal
• Shank visibly stretched or necked below the head

🛠️ Service Notes

• Check the length, thread and strength grade of the replacement against the screw you removed — engine fasteners are chosen for a specific clamp load, and a longer or softer screw is not a substitute
• Clean the threads in the component and make sure the mating faces are clean and flat before assembly; dirt, paint or old sealant in a joint feels like tightness and leaves the joint loose
• Tighten to the torque figure and the tightening sequence given in the workshop manual for your engine, working up progressively rather than pulling each screw down in one go
• Use thread locking or sealing compound only where the manual calls for it, and renew the locking washer, tab washer or nut that works with the screw
• Renew rather than reuse screws that are corroded, thread-damaged or visibly stretched, and any screw the manual tightens by torque-plus-angle
