Paramount PAR37288 Hex Key 19mm Short Arm

Product Description

The PARAMOUNT PAR37288 is a short-arm hex key designed for high-torque fastening applications in tight or confined spaces. It features a 19 mm hex size and is manufactured from Protanium High Torque Steel, a material engineered to withstand demanding drive applications without deforming the key or the fastener socket. The overall length is 6-29/32 inches, making it compact enough for restricted access while still delivering adequate leverage. This tool is appropriate for use by HVAC technicians, plumbers, electricians, and general trade professionals who work with metric hex fasteners on equipment and structural components.

This hex key is suited for residential and commercial trade applications wherever metric hex-head fasteners are present. Common use cases include tightening or loosening set screws on mechanical components, motor mounts, valve bodies, equipment panels, and similar assemblies. The short-arm style gives the user a low-profile drive angle, which is advantageous when clearance above the fastener is limited. The gray handle finish aids identification in a tool bag or kit.

Installation Notes

This tool is used by trade professionals for tightening and loosening metric hex fasteners on equipment and assemblies. Before servicing any equipment, de-energize electrical systems, shut off gas or fluid supply as applicable, and follow all relevant lockout/tagout procedures. Ensure the hex key is fully seated in the fastener socket before applying torque to prevent rounding of the socket or the key tip. Inspect the key for damage or deformation before each use.
