The PARAMOUNT PAR37149 is a metric hex key designed for driving hex socket fasteners in tight or deep-access applications. It features a long arm configuration with a hex end, giving the technician increased torque leverage and reach compared to standard-arm versions. The key is machined from Protanium High Torque Steel, a material rated for high-load fastener driving without deforming the tool tip. Overall length is 2.8 inches, making it compact enough for confined spaces. This tool is commonly used by HVAC technicians, plumbers, pool equipment installers, and mechanical service professionals when working with metric fasteners in equipment assemblies.
The PAR37149 is suited for service and installation work on equipment that uses 1.27 mm metric hex fasteners. The long arm design allows the technician to apply torque along the long end or use the short end as a T-handle for rapid driving. It fits into standard hex key sets for metric applications and is appropriate for residential and light commercial equipment service where small metric fasteners are common.
Designed as a general-purpose metric hex key for use with 1.27 mm hex socket fasteners found in HVAC, plumbing, pool, and mechanical equipment assemblies.
This tool is used by licensed HVAC technicians, plumbers, and pool service professionals during equipment installation and service. Always power down or shut off the equipment being serviced before loosening or tightening fasteners. Use the long arm for torque application and the short arm for rapid spinning in open-access situations. Inspect the tool tip before use and replace if worn to avoid stripping fastener sockets.
