Paramount PAR37174 Hex Key 9mm Long Arm Hex End

Product Description

The PARAMOUNT PAR37174 is a metric hex key designed for high-torque fastener driving in professional trade applications. Built from Protanium High Torque Steel, this long-arm hex key delivers the mechanical advantage needed for stubborn fasteners in tight installations. The 9 mm hex end engages metric socket-head fasteners securely, while the long arm style provides extended reach and improved leverage compared to standard-length keys. With an overall length of 6.2 inches, the PAR37174 suits HVAC equipment panels, pump assemblies, valve packing glands, and similar trade hardware where metric fasteners are specified.

This hex key is suited for use in residential and commercial maintenance environments wherever metric hex-drive fasteners are encountered. Typical applications include HVAC equipment service, mechanical room hardware, pool and spa equipment assemblies, and general plumbing fixture work. The gray handle and long arm configuration make it a practical addition to a field technician's hand-tool kit for recurring service calls.

Installation Notes

This tool is installed by hand and requires no power source or special setup. Ensure the hex end is fully seated in the fastener socket before applying torque to avoid rounding the drive. Keep the tool clean and free of grease buildup to maintain positive engagement with fastener heads. Follow applicable equipment manufacturer service procedures when accessing panels or assemblies.
