The M1.5 x 7.3mm pin pack, model 3RAC-PN1573, contains five steel pieces intended for retention and pivot roles in small model assemblies.
Use cases include hinge points, tiny linkages and other small moving joints. The straight pin form makes replacements and spares management straightforward; verify the mating hole diameter and length before installation for a proper fit.
Fitting is simple: align components, slide the pin into the mating holes and confirm movement and retention. Keeping spare pins of the same size on hand reduces downtime during repairs or setup changes.
