These spring load pull pins allow you to quickly retract and engage the plunger for locating, fastening and quick change operations. They consist of two parts which include a housing (barrel) and a plunger assembly. The plunger assembly screws into the housing. The housing is designed to be welded into place for strength. The 3/8-16 threaded end allows the user to add a custom handle or other method of actuation.
Pulling up on the plunger assembly retracts the plunger into the housing. Releasing the plunger assembly allows the spring loaded plunger to extend. The plunger assembly and housing are made from 303 stainless steel. Pull up force is approximately 5 lbs.
