Installation Procedure

1. Select the appropriate wrench or socket matching the 22mm head width. 2. Engage the wrench securely with the hex head. 3. Apply consistent, controlled torque to tighten the screw into the pre-threaded hole or nut until the desired clamping force is achieved, avoiding over-tightening. 4. Visually inspect the fastener to ensure it is seated flush and secure.
