What it is

The Glow-worm S014277 is an M4 x 10mm steel screw with a countersunk head and cross recess drive, finished in bright zinc plate. It is a fixing component used on Glow-worm gas boilers, including the GW and Ultracom families. It is supplied as a single service part under the manufacturer's part number S014277.

Signs this part needs replacing

  • The screw head is rounded or chewed, so the driver no longer bites
  • The thread is stripped or cross-threaded in the fixing point
  • Corrosion or heavy zinc loss on the shank or head
  • The screw has been lost or dropped during a service or strip-down
  • The screw will not torque down and keeps turning in the hole

Before you order

  • Confirm the part number S014277 against your appliance's parts list
  • Check the thread size and length required at the fixing point, as M4 x 10mm is not universal across all positions
  • Check the head type and drive recess match the original fixing
  • Verify your boiler model against the fitment list above before ordering
