Installation Notes

This wrench is used by mechanics, HVAC technicians, plumbers, and electricians for fastener installation and removal. Always ensure the box end is fully seated on the fastener before applying torque to avoid rounding. De-energize electrical systems and shut off fluid or refrigerant supply before beginning any service work that requires wrench use on system components. Keep the tool clean and inspect for cracks or deformation before use.
