How to use

Select the appropriate jaw size (21 mm or 23 mm) and place the open end of the wrench fully over the nut or bolt head. Ensure a secure, square fit before applying force to avoid rounding the fastener. Apply steady force in the intended direction to tighten or loosen; for higher torque needs, use a correctly sized tool rather than additional leverage extensions. After use, wipe clean and store in a dry place to maintain the chrome finish and prevent corrosion.

Usage recommendations

Use the Proline 5343215 for matched metric fasteners and avoid using the wrench on rounded or damaged heads. For safety, wear appropriate hand protection and inspect the tool periodically for wear or distortions; replace if deformation is detected.
