The PEM® VariMount® fastening system eliminates issues associated with welding. The assembly is comprised of a standard PEM® nut, stud or standoff mounted permanently into a base plate.  The assembly can then be fastened or bonded to assorted panel types in a variety of ways.


VariMount® assemblies are available with either steel or stainless steel base plates depending on the fastener that is selected.  The VariMount® base plate’s radial holes provide various mounting options.  Base plates can also be purchased separately.
