What it is

The Worcester Bosch sealing screw 87034060440 is a small fastening component used to seal a connection point on Worcester Bosch gas appliances. It is listed for use on the British Gas Jetatherm Wh2-BXN-GB NAT GAS BF. The screw closes off and seals its fixing point so that gas or water cannot escape past the joint.
