What it is

The Alpha hex socket screw M5 x 16mm, part number 1.030602, is a fixing used across the Alpha boiler range, including InTEC 2, E-TEC, ECO 2 and Evoke models. It secures internal components where a hex socket head allows access and controlled tightening. This is a service part for maintenance and repair work on the appliance.

Signs this part needs replacing

  • Hex socket rounded or stripped, preventing the screw from being tightened or removed
  • Corrosion or seizure in the thread, common on components exposed to heat or condensate
  • Screw missing after a service or repair
  • Damaged or crossed thread causing the fixing to bind
  • Component becoming loose because the screw no longer holds torque

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check the thread size and length required for the specific fixing point
  • Verify the part number 1.030602 matches the item being replaced
