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. Style H does have a locking nut. Material: locking pin hardened, steel grade 5.8, mushroom knob anthracite gray thermoplastic.
