Paramount PAR17599 9 Piece Metric Ball End Hex Key Set

Product Description

The PARAMOUNT PAR17599 is a 9-piece metric ball end L-key hex key set built for technicians who need reliable fastener access in tight or angled positions. The ball end tips allow engagement at angles up to 25 degrees, which is useful when working around obstructions in HVAC equipment, plumbing fixtures, or electrical enclosures. The set covers a hex size range of 1.5 mm to 10 mm, giving technicians the most common metric drive sizes in one kit. Each key is manufactured from steel for durability under regular shop and field use. Overall length is 7.25 inches per key. The set ships in a plastic bench stand that organizes all 9 pieces and keeps them accessible at a workstation.

This hex key set is suited for trade professionals and facilities maintenance technicians who regularly service equipment fastened with metric socket head cap screws. Typical applications include HVAC unit assembly and service, pump and motor maintenance, electrical panel work, and pool equipment servicing where metric hardware is common. The bench stand design makes it practical for a stationary service bench or tool cart. The included sizes -- 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 mm -- cover the fastener range found across most residential and light commercial equipment.

Installation Notes

Hex keys should be inspected before use -- worn or rounded ball ends can strip fastener sockets and should be replaced. Always select the correct size key for the fastener to avoid rounding the drive recess. Power down or depressurize equipment before removing fasteners that secure access panels, motors, or pressurized components. For critical assemblies, consult the equipment manufacturer service manual for fastener torque specifications.
