⚙️ Key Features

• Hexagon screw from the Engine group
• 0.229 kg
• Listed for 75 V series applications
• Supersedes 21740808, catalogued earlier as a bolt
• 2 used per assembly

🔌 Function

Clamps two engine components together, holding the joint tight against vibration and thermal movement.

⚠️ Common Signs of Failure

• Joint working loose or weeping where it should be dry
• Screw found backed off, or its washer fretted bright
• Thread picked up, stretched or stripped on removal
• Head corroded or rounded so it will not take a socket
• Clamping face dished around the hole where the screw has been loose

🛠️ 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
