Paramount PAR30199 22 Piece Ball End Hex Key Set

Product Description

The PARAMOUNT PAR30199 is a 22-piece L-key ball end hex key set built for trade and maintenance professionals who need a complete metric and inch hex key range in a single organized package. The set covers hex sizes from 0.05 to 0.375 inches and 1.5 to 10 mm, handling the full spread of fastener sizes common in HVAC equipment, pump assemblies, electrical panels, and mechanical systems. All keys are constructed from steel and stored in a plastic bench stand that keeps the set organized and accessible on a workbench or service cart. The ball end design allows engagement at an angle, useful when working in tight or obstructed fastener access points.

This set is suited for field and shop use by HVAC technicians, plumbers, electricians, and pool equipment service pros. The bench stand stores neatly on a cart or workbench, making it practical for service trucks and maintenance shops alike. The metric and inch dual-coverage means one set handles most fastener standards encountered in residential and light commercial equipment service. With 22 keys in the set, techs have access to the most commonly used hex sizes without hunting through a loose assortment.

Installation Notes

This set is a hand tool and does not require installation.

Ensure the correct key size is fully seated in the fastener before applying torque to avoid rounding. Inspect keys periodically for wear or deformation and replace any damaged keys before use.
