What it is

The Worcester Bosch hydraulic block screw is an M5 x 32 mm fastener used in the casing of Greenstar and Greenstar ErP boilers. It holds the hydraulic block assembly in position within the casing, which differs from model to model to suit different installation locations, robustness requirements and finishes. As a manufacturer-supplied fixing, it matches the thread form and length specified for these assemblies.

Signs this part needs replacing

  • Corrosion or surface rust on the screw head or shank
  • Rounded or chewed head that no longer takes a driver cleanly
  • Crossed or flattened threads that will not pull the casing down evenly
  • Casing or hydraulic block sitting loose, rattling or vibrating in service
  • Screw seized in the casing and sheared during removal

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the correct fixing for your model.
  • The alternative part number 1019893 may be listed in place of 87167716870 on some documentation.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
