Locking inserts retain locking torque over numerous assembly cycles. Refer to relevant specifications for insert life. Each Recoil screw-locking insert type has a specifically designed locking configuration. This ensures that the insert meets its design specification requirements. Therefore the shape, depth, and number of locking chords will inevitably vary for differing thread types and sizes.NOTE: Recoil locking inserts are supplied coloured in a red surface dye as standard for differentiation from standard inserts.
Both screw-locking and free-running inserts are available on plastic strips for automated tooling systems.
