Worcester Bosch Screw M5 x 12mm 87434010360

This is an M5 x 12mm screw manufactured by Worcester Bosch, supplied under part number 87434010360 in a pack of ten. It is a fixing used to secure components within the casing and internal assemblies of Worcester Bosch Greenstar Highflow CDi ErP appliances. The screw forms part of the boiler's fastener set, holding panels, brackets and internal parts firmly in position so that the appliance operates as designed.

• The screw head is rounded or chewed, making it difficult to turn with a driver or spanner
• Corrosion or surface rust on the thread, common where a fixing sits in a damp or condensate-affected area
• The thread is stripped or the screw will not tighten, so the component it holds remains loose
• A fixing is missing after a service or repair, leaving a panel or bracket short of its full fastener set
• Vibration or movement from a component that should be rigidly fixed

• Check the GC number or serial plate on the appliance to confirm the model before ordering
• Confirm the thread size and length match the fixing being replaced, as M5 x 12mm is a specific size
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
