What it is

The Worcester Bosch 29110612440 is an M8 x 25 mm hex head bolt used as a fixing on Worcester Bosch oil boilers. It sits within the screws, nuts, bolts and clips category for the CAM 5 and Greenstar oil ranges. The hex head allows standard spanner or socket access for tightening and removal during assembly or service.

Signs this part needs replacing

  • Corrosion or rust on the bolt head or thread
  • Rounded or damaged hex head that a spanner or socket can no longer grip
  • Damaged or crossed threads preventing correct tightening
  • Bolt seized, snapped or missing, leaving a component insecure

Before you order

  • Check your boiler model against the fit list above
  • Confirm the required thread size (M8) and length (25 mm) for the fixing point
  • Check how many bolts are needed for the job
  • Inspect adjacent fixings for corrosion while access is available
