Williams Comfort Products HKT-5MM Arm T-key

Product Description

The WILLIAMS COMFORT PRODUCTS HKT-5MM is a 5.0mm hex arm T-key wrench designed for use in HVAC and heating equipment service applications. Measuring 6 inches in arm length, this T-key provides the leverage and access needed to drive 5.0mm hex fasteners in tight or recessed locations common on heating appliances and combustion equipment. Sold individually, it is a standard hand tool used by licensed HVAC technicians and service professionals performing routine maintenance, component replacement, or panel access tasks on gas-fired and vented heating units.

This T-key is suited for residential and light commercial service work where 5.0mm hex fasteners are specified by the equipment manufacturer. It is commonly used when servicing wall furnaces, floor furnaces, and vented room heaters where specialty hex keys are required to access internal components. The 6-inch arm length provides additional torque without the need for extensions, making it practical for field technicians working with limited clearance.

Compatibility

Installation Notes

Always shut off electrical power and close the manual gas shutoff valve before opening any access panel on a heating appliance. This tool is intended for use by qualified HVAC service technicians familiar with applicable codes including the IFGC. Apply hand pressure only and avoid using the T-key with power tools or extensions that could strip metric fasteners. Inspect the hex tip for wear before each use to ensure proper fastener engagement.
