SRR Flat nut for shafts
The SRR Flat nut is a rectangular fastener with the entry orifice of the shaft situated in the middle. It is a one-use fastening element designed for use in assemblies which are not normally dismounted, as in order to do this it would be necessary to break the SRR.
It is used in applications which do not require great force such as electrical devices, electricity, gas or water meters, measuring instruments, etc.
