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. Style C or D is recommended for applications in which the pin is disengaged over extended periods and should be prevented from springing back. Style B features a non-lockout type with locknut. Material: Indexing pin hardened grade 5.8, mushroom knob black grey thermoplastic.
