Indexing Plungers without Collars

Shop our large selection of plastic, steel, and stainless steel indexing plungers without collars. Indexing plungers are used to prevent any change in locking position due to lateral forces. A new locking position can only be set after the pin has been manually disengaged. A washer is available to aid by screwing in the indexing plunger. The washer slides beneath the mushroom knob so that the carrier pins engage in the slot. AFT offers no collar indexing plungers in both inch and metric sizes, with an extended pin or standard size pin, and with or without a locknut.
