Type 3506-SC Stud Assemblies
|
Type 3506-SC stud assemblies consist of a stud and coil spring captive in a steel cup. The assemblies are installed by flaring the end of the cup neck into a countersunk panel hole. Stud locking action compresses the spring, exerting a clamping force on the fastened parts. In locking, the stud spiral cam engages a rigid wire which is offered by the receptacle. MIL-F-25173A** approved.
