Vaillant Screw M6x20 Pack of 10 0020081364

The Vaillant 0020081364 is an M6x20 screw made to the ISO 14583 specification and supplied in packs of 10. It is a fixing used on Vaillant ecoTEC VU appliances, where fasteners are removed and refitted during servicing and component replacement. The M6 thread and 20 mm length identify it as a specific fixing rather than a general-purpose screw, so it should be matched to the position it is being taken from.

• The screw head is corroded or rusted, so the correct driver bit does not seat properly
• The head is rounded or chewed from a previous removal attempt
• Threads are stripped or cross-threaded and the fixing will not tighten down
• The fixing is missing or was dropped during a service or component swap
• The screw has worked loose, allowing the component it retains to move

• Check the model and GC number on the appliance data badge against the compatibility list; the listed references are 41-044-68, 41-044-69 and 41-044-70.
• Confirm the thread size, length and head form match the fixing being replaced before fitting.
• Ordering a pack of 10 keeps matching spares to hand for the same assembly.
