Provide a cost-effective solution to your connector mounting requirements. Can replace as many as ten pieces of loose hardware per connector and can be installed in a fraction of the time. Used for applications requiring closed thread ends. Blind end limits screw penetration and excludes foreign matter. Standoffs available with or without threads for mounting into P. C.

Annular projecting teeth eliminate the need for serrated or starwashers to make good electrical contact with the circuit foil.
