Stripper Bolts

These are used to limit plate travel. The length of the bolts is given from the bottom of the head to the end of the body. The tapped hole is always smaller than the body. The placement of the stripper bolt follows the same rules as the screws. The most common problem with stripper bolts that are used in plate sequencing is that they will frequently come loose and need to be tightened. The designer should be aware of this and try to place them as close to the outside edge for easy accessibility to the technician. The majority of mold crashes that have plate sequencing using stripper bolts come from neglect of the mold technician not checking the stripper bolts.
