The PARAMOUNT PAR35213 is a T-handle hex key designed for driving hex-socket fasteners in tight or high-torque applications. It features a 5/16-inch hex end and a cushion-grip T-handle that provides a comfortable, secure grip during extended use. The overall length is 6 inches. The tool is constructed from steel for durability and is suited for use in HVAC equipment assembly, pool equipment installation, and general mechanical service work. The T-handle configuration allows technicians to apply rotational torque with both hands where a standard L-key would be impractical.
This hex key is intended for trade professionals who need reliable hand tools during service calls and equipment installation. The 5/16-inch hex size is commonly required when servicing pool equipment, pump assemblies, HVAC blower components, and similar mechanical hardware. The cushion grip T-handle reduces hand fatigue during repetitive fastening tasks. It is packaged as a single unit and is appropriate for field tool kits or shop use.
Designed as a general-purpose T-handle hex key for use with 5/16-inch hex-socket fasteners found in HVAC, pool, and plumbing equipment assemblies.
This hand tool is used by HVAC technicians, plumbers, and pool service professionals. Always de-energize and lock out equipment before loosening or tightening fasteners on powered components. Inspect the hex tip for wear or rounding before use to avoid stripping fastener sockets. No special certifications or codes apply to the use of this hand tool, though all service work should comply with applicable local codes.
