PEM panel fasteners designed specifically for tool-only access applications provide fixed screw solutions for a new EC machinery directive imposing strict safety requirements for machine guarding and the ergonomics of operator equipment. This directive requires fasteners to remain attached when guards are removed. These panel fasteners with threaded captive screws have been engineered to install permanently into thin metal panels.  Their elimination of loose screws promotes speedier maintenance of machines without a need to handle hardware and prevents screws from becoming lost either inside or outside the machine.  These fasteners are UL-approved.
