Paramount PAR32199 22-piece L-key Hex Key Set

Product Description

The PARAMOUNT PAR32199 is a 22-piece L-key hex key set designed for fastener driving in mechanical, HVAC, plumbing, and electrical service work. The set covers a hex size range of 0.050 to 3/8 inches (1.5 mm to 10 mm), giving technicians access to both imperial and metric fasteners from a single kit. All keys are constructed from steel for durability under torque. The overall length of the longest key is 7.25 inches. The set stores in a plastic holder, keeping sizes organized and reducing job-site clutter. It is suited for service calls where a wide range of fastener sizes may be encountered.

This hex key set is appropriate for residential and light commercial service work across multiple trades. HVAC technicians use L-key sets when servicing equipment covers, motor mounts, and access panels secured with socket-head cap screws. Plumbers and electricians reach for these sets when working on valve packing glands, enclosure hardware, and equipment mounting fasteners. The L-key handle format provides both a short-arm driving option for torque and a long-arm option for reach in confined spaces.

Installation Notes

L-key hex sets require no installation. Technicians should select the correct key size before applying torque to avoid rounding fastener sockets. Use the short arm for higher torque and the long arm for accessibility in tight spaces. Inspect keys periodically for wear or rounding and replace any damaged pieces before reuse.
