What it is

The Biasi BI1131107 is an M5 x 25 mm hexagon socket cap screw used as a fixing on Biasi gas boiler assemblies. It is specified for Garda, Parva and RIVA HE appliance families built up to serial No. N018390805. The screw secures internal components where a flush, high-torque socket head fixing is required.

Signs this part needs replacing

  • The socket head is rounded or chewed, so the Allen key no longer grips
  • The screw is seized, snapped or has stripped threads
  • Corrosion or rust on the head or shank
  • The component it secures has worked loose or is rattling
  • The screw has been lost during a strip-down or service

Before you order

  • Confirm your appliance serial number is up to N018390805, as later builds use a different fixing
  • Check the thread size and length against the screw being removed — M5 x 25 mm
  • Confirm the head type matches the recess on the component being secured
  • Check how many screws are needed for the job
