Supco zt10 Dual Nut Driver 5/16 and 1/4 Inch Sockets

Product Description

The SUPCO zt10 is a dual-socket nut driver designed for HVAC service work where standard tools cannot reach confined fastener locations. It features two hinged sockets — 5/16 inch and 1/4 inch — that pivot to access tight angles and recessed screw positions common in furnaces and air handlers. The hinged design allows the technician to drive or loosen fasteners without a straight-line approach. The zt10 also serves as a removal tool for flame-sensing rods, making it a practical multi-use hand tool for heating system service calls.

This tool is suited for residential and light commercial HVAC service. It is most commonly used when servicing gas furnaces, where panel screws, blower compartment fasteners, and flame sensor assemblies are positioned at difficult angles. Any technician who regularly works inside furnace cabinets will find the hinged socket arrangement reduces the need for multiple tool changes in cramped spaces.

Key Features

• Two socket sizes in one tool: 5/16 inch and 1/4 inch
• Hinged sockets pivot to reach difficult angles and tight screw locations
• Capable of removing flame-sensing rods without additional tools
• Compact dual-function design reduces tool count on service calls

Compatibility

Designed for general HVAC service applications requiring 5/16 inch or 1/4 inch fastener drive in restricted-access locations.

Installation Notes

Always de-energize the unit and confirm power is off at the disconnect before working inside any furnace or air handler cabinet. This tool is intended for use by qualified HVAC technicians. When removing flame-sensing rods, handle with care to avoid cracking the ceramic insulator. Follow applicable service procedures per the equipment manufacturer and local codes.
