The PARAMOUNT PAR35260 is a T-handle hex key designed for driving hex fasteners in mechanical, plumbing, HVAC, and general trade applications. Built from steel with a 4.00 mm hex end, this tool delivers reliable torque through a cushion grip T-handle that reduces hand fatigue during extended use. The overall length of 6 inches provides enough leverage for most field fastener work without the bulk of a larger wrench set. It is a single-piece, metric hex key suited for technicians who work with metric-spec equipment and need a dedicated, ergonomic driver for frequent adjustments.
This hex key is a practical addition to any service technician's toolkit. Its T-handle configuration makes it well-suited for repetitive fastener driving in tight equipment panels, pump housings, valve assemblies, and mechanical equipment covers. The 4.00 mm metric size targets fasteners common on imported and metric-spec HVAC, plumbing, and pool equipment. Tan-handled for quick visual identification in a multi-tool bag, it ships as a single unit with a minimum order of one piece.
Designed as a general-purpose metric hex key for use with 4.00 mm hex fasteners found on HVAC, plumbing, pool, and mechanical trade equipment.
This tool is used by HVAC technicians, plumbers, electricians, and pool service professionals for loosening and tightening hex-socket fasteners. Always ensure equipment is powered down and depressurized before accessing fastener points on live systems. Inspect the hex tip before use to confirm it seats fully in the fastener socket and avoid rounding fastener heads by using the correct size. No special certifications are required to use this tool, but follow applicable safety procedures for the system being serviced.
