Paramount PAR37299 9 Piece Metric Hex Key Set

Product Description

The PARAMOUNT PAR37299 is a 9-piece metric short arm L-key hex key set designed for fastener-driving applications in HVAC, plumbing, electrical, and general mechanical service work. The set covers hex sizes from 1.5 mm to 10 mm, giving technicians the range needed for most metric fastener work on equipment panels, motor mounts, and component hardware. Keys are manufactured from steel for durability under regular torque loads. The short arm geometry provides clearance in confined spaces where a long arm key will not fit. Keys store in an included plastic holder that keeps the set organized on a service van or workbench.

This hex key set is suited for trade professionals who regularly service metric-fastened equipment. Typical applications include tightening or loosening set screws on motor shafts and pulleys, adjusting panel hardware on HVAC units, and general mechanical assembly and disassembly tasks. The 9-piece range from 1.5 mm to 10 mm addresses the most common metric hex fastener sizes encountered in residential and light commercial equipment service. The plastic holder allows individual keys to be removed and replaced without losing pieces on a job site.

Installation Notes

Select the correct key size before applying torque to avoid rounding the fastener socket. Power down or de-energize equipment before accessing internal fasteners on electrical or mechanical assemblies. Inspect keys for wear or deformation periodically and replace any damaged key before use to prevent fastener damage.
