Paramount PAR37115 Hex Key 7/16 Inch Long Arm

Product Description

The PARAMOUNT PAR37115 is a long-arm hex key designed for high-torque fastening applications in trade and mechanical service work. Built from Protanium High Torque Steel, this hex key measures 7.5 inches in overall length and accepts 7/16 inch hex fasteners. The long-arm configuration provides extended reach and increased leverage compared to standard-arm designs, making it well-suited for confined spaces or applications requiring greater turning force. HVAC technicians, plumbers, electricians, and mechanical contractors reach for tools like this when working with set screws, equipment access panels, and mechanical assemblies that demand a reliable grip and durable construction.

This hex key is suited for general trade use anywhere 7/16 inch hex drive fasteners are encountered. Common applications include equipment installation and service, mechanical fastener adjustment on HVAC units, pump assemblies, and similar trade equipment. The long arm allows the short end to be used for high-torque seating and the long end for fast spinning in open access areas. The gray handle and Protanium steel construction make it a durable addition to a service technician's hand tool kit.

Installation Notes

This tool is used by licensed HVAC technicians, plumbers, electricians, and general mechanical contractors. Always power down or de-energize equipment before accessing fasteners on electrical or mechanical assemblies. Use the short arm for initial torque application and the long arm for rapid rotation in accessible areas. Inspect the tool for wear or deformation before each use and replace if the hex end shows rounding or cracking.
