Spring-Loaded Plunger Pins, or Pop pins are short, threaded, large diameter external housing with a protruding spring-loaded pin through the middle. The central spring-loaded pin can be retracted to disengage the pin from the assembly it is installed into.
Pop Pins Diameters
Pop Pins are available on the FCH Network with Imperial/US diameters that range from #2 to 6 and with Metric diameters that range from M3 to 6. The length of Pop Pins is usually measured from the point to the underside of the head.
