Paramount PAR37170 Hex Key 7mm Long Arm Protanium Steel

Product Description

The PARAMOUNT PAR37170 is a long-arm hex key designed for fastening and loosening 7.00 mm hex fasteners in professional trade applications. Built from Protanium High Torque Steel, this tool delivers the tensile strength needed to drive stubborn or high-torque fasteners without deforming the tip. The long arm configuration provides extended reach into recessed cavities and generates greater torque leverage compared to standard-length keys. Overall length is 5.5 inches. The gray handle and metric sizing make it straightforward to identify in a tool kit. This is a single-piece, hand-tool-grade wrench suited for use by HVAC technicians, plumbers, electricians, and general mechanical trades.

This hex key is used wherever 7.00 mm hex-drive fasteners appear, including equipment panels, valve assemblies, pipe brackets, motor mounts, and enclosure hardware. The long arm design is particularly useful in tight installations where a short-arm key cannot generate adequate torque or cannot reach the fastener head. It is appropriate for both residential and commercial service work across HVAC, plumbing, and electrical disciplines. Metric sizing is standard for many imported equipment assemblies and European-spec components.

Key Features

• 7.00 mm metric hex size for precise fastener engagement
• Long arm style delivers extended reach and increased torque leverage
• Protanium High Torque Steel construction resists tip rounding under load
• 5.5 inch overall length fits a wide range of service scenarios
• Gray handle aids quick visual identification in a tool set

Compatibility

Designed for use with 7.00 mm hex-drive fasteners across standard metric hardware applications in HVAC, plumbing, electrical, and general mechanical service work.

Installation Notes

This hex key is a hand tool used by technicians across licensed trades. No power source is required, but ensure equipment is de-energized and any pressurized systems are isolated before accessing fasteners. Use the short arm for initial seating and the long arm for torque application to reduce the risk of fastener or tool damage. Inspect the tip for wear or deformation before use and replace if the hex faces show rounding.
