SRM Circular uncapped push-on fastener for shafts
The SRM push on fastener is a one-use fastener designed for use in
assemblies which are not normally dismounted, as in order to do this
it would be necessary to break the SRM.
It is normally fitted to shafts with no groove but it can also be used with
grooved shafts, which would help to improve its resistance to axial forces.
It is used in applications which do not require great force such as electrical
devices, electricity, gas or water meters, measuring instruments, etc.
