What it is
This is an M5 x 16mm hexagon socket cap screw supplied by Biasi under part number KI1042124. It is a threaded fastener used in the assembly and servicing of Biasi Activ A series boilers. The hexagon socket head allows the screw to be driven with an Allen key in confined spaces where a conventional hex head would not fit.
Signs this part needs replacing
- The screw is missing from its fixing point after a service or strip-down
- The socket head is rounded or chewed, so the Allen key no longer grips
- The thread is stripped or cross-threaded and will not torque down
- Corrosion or heat damage has weakened the screw
- The screw has been over-tightened and the head has sheared off
Before you order
- Confirm the thread size and length required against the manufacturer's parts list for your model
- Check the drive type needed at the fixing point — this is an internal hex socket head
- Verify the appliance model against the fit list above before ordering
