Total grip thickness is comprised of the thickness of ALL materials to be fastened. This must include the thickness of the material “P”, to which the stud assembly is attached; the material “F”, to which the receptacle is attached plus allowance for paint or other protective finishes.
Note: If the grip thickness is near the top of the stud grip range, the next larger stud should be used. This will maintain the positive locking action of the fastener under vibration. To select the proper stud length, FIRST select the grommet, next select the receptacle. Once this is done, refer to the 4002 stud selection chart.
