The MALCO W19 / MULT. OF 10 is a small hex key folding set designed for use in tight-access fastening and adjustment tasks across HVAC, plumbing, electrical, and general mechanical service work. The folding design consolidates multiple hex key sizes into a single compact tool, reducing the need to carry loose individual keys on the job. This type of tool is a standard addition to a service technician's kit when working on equipment that uses hex socket fasteners for panel covers, motor mounts, and component brackets.
This folding hex key set is suited for light-duty service applications where compact tool storage and portability are priorities. It is commonly used by HVAC technicians, plumbers, and electricians who need quick access to a range of small hex sizes during equipment service, installation, or maintenance calls. The set is sold in multiples of 10, making it practical for shop stocking, fleet toolbox replenishment, or resale through supply houses.
Designed as a general-purpose small hex key folding set suitable for use with standard hex socket fasteners encountered in HVAC, plumbing, electrical, and mechanical service applications.
Hex key sets are used by trade professionals including HVAC technicians, plumbers, and electricians during equipment service and installation. Always de-energize electrical equipment and shut off supply lines before loosening or removing fasteners secured with hex keys. Use the correct key size to avoid rounding fastener heads. Follow applicable codes and equipment manufacturer guidelines when disassembling or reassembling components.
