What it is

The Biasi BI1001125 is an M5 x 16mm hexagon socket cap screw used as a fastener on Biasi gas boilers. It secures components where a flush, internally driven head is required, and is tightened with a hex key rather than a screwdriver. It is a service part for the Biasi appliance families listed below.

Signs this part needs replacing

  • The hexagon socket is rounded or chewed, so the key slips under load
  • Corrosion or pitting on the head or threads
  • Cross-threading or damaged threads preventing correct torque
  • The screw is missing or has been lost during a service or repair
  • The fastener keeps working loose after being tightened

Before you order

  • Check your appliance model against the fitment list above
  • Confirm the existing screw is M5 x 16mm and has a hexagon socket cap head
  • Check how many screws are required for the job, as this listing is for a single screw
  • Inspect the mating thread for damage before fitting a new screw
