Worcester Bosch Screw Pack of 3 871861504A0

A pack of three Worcester Bosch screws, supplied under part number 871861504A0. These are the small threaded fixings used to secure internal components and covers on Worcester Bosch gas boilers, and they are listed against the Greenstar Compact and i Series ranges. They are a service consumable: original fixings can be lost, dropped or damaged during maintenance, and replacements keep casings and assemblies correctly fastened.

• A fixing is missing after a service or component change, leaving a cover or bracket loose.
• The screw head is rounded or chewed, so it cannot be tightened or removed with the correct driver.
• Corrosion or rust on the thread, common where a fixing sits in a damp or condensate-affected area.
• Vibration has worked the screw loose and the panel or component it holds is no longer secure.
• The thread has stripped in the housing and the original fixing will not hold torque.

• Check the boiler's GC number and model plate against the compatibility list to confirm 871861504A0 is the correct fixing for your appliance.
• The alternative number 1030841 may also appear on older documentation or parts listings for the same item.
• Confirm the quantity needed: this pack contains three screws, and some assemblies use more than one.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
