Paramount PAR37106 Hex Key 7/64 Inch Long Arm

Product Description

The PARAMOUNT PAR37106 is a long-arm hex key designed for driving hex fasteners in tight or recessed locations. Manufactured from steel, it features a 7/64 inch hex end and a long arm configuration that provides extended reach and increased torque leverage compared to standard-length keys. The overall length measures 3-9/16 inches. This type of hand tool is a routine part of any mechanic's, HVAC technician's, or plumber's kit, used wherever hex socket fasteners appear on equipment housings, valves, panels, and assemblies.

The PAR37106 is suited for general maintenance and service work across residential and light commercial applications. The long arm design allows access to fasteners seated deeper in equipment cavities or panel openings. It is commonly used by HVAC technicians servicing equipment panels, plumbers working on valve assemblies, and electricians tightening set screws on connectors and conduit fittings. The inch-measurement sizing makes it compatible with standard fractional hex fasteners found across North American trade equipment.

Compatibility

Designed as a standard long-arm hex key for use with 7/64 inch hex socket fasteners across general trade and mechanical service applications.

Installation Notes

No power lockout is required for hand tool use, but always de-energize and lock out equipment before accessing fasteners on live electrical or mechanical assemblies. Insert the hex end fully into the fastener socket before applying torque to avoid rounding. For stubborn fasteners, apply penetrating fluid and allow it to dwell before attempting removal. This tool is intended for hand operation only — do not extend the handle or apply excessive force beyond normal hand torque.
