·About KZDF (Induction Hardened)
When alterations on the above are specified,
the shafts are induction hardened after machining. (Except the threaded sections)
As a result, these may occur:
(1): Due to thermal conduction to the thread, the threads may be hardened by 2 to 3 mm. (2): Induction Hardened may shrink the keyway width (Around -0.01 to -0.02)
If the key becomes hard to fit, adjust it by gauging.
