Quarter Turn - PA-3500 Line Type 3522-S Stud AssembliesType 3522-S stud assemblies provide a nearly solid lock without allowing the sheet separation that occurs with 3506-SC assemblies while under tensile overload sufficient to overcome the expansion force of their springs. With 3522-S assemblies, the stud cam first quarter-turns onto the receptacle wire under spring tension supplied by a curved washer. Further locking rotation then starts to turn the cammed fastener head around a stud cross-pin. The head is moved downward as it turns, compressing a coil spring which is stronger than the curved washer, and finally compressing the curved washer flat. At the fully-locked position, the assembly has no remaining spring movement achievable by tensile overload. 3522-S assemblies are not MIL-F-25173A approved. CAUTION: Any external factor that prevents the stud from turning with initial locking torque could allow the fastener head to rotate first. This could convey an erroneous impression of locking while the stud cam has not locked onto the receptacle wire. All operators of this special purpose fastener should be trained to recognize proper stud cam locking.
