The shaft end processing section (effective thread length + approx. 10 mm) may experience reduced hardness due to the annealing effect of the processing.

If there are requirements for rust prevention, give priority to products with hard chrome plated surface treatment. Please click

Rust Prevention Methods

If used together with linear bushings, please select products with high-frequency quenching.
