## Long description

Replacement vice screws Proxxon PR20394 are original replacement screws designed for use with Primus vices.

Key specifications

How to use

Reassemble the vise and test for smooth jaw movement and secure clamping before returning the tool to regular use.

For reliable long-term performance, inspect the screw and mating nut periodically for signs of wear or corrosion, lubricate moving parts regularly, and replace other worn components as needed to maintain correct clamping force and alignment.
