The WILLIAMS COMFORT PRODUCTS WS-45 is an 8-piece hex key set designed for general mechanical assembly and fastener work across a range of trade applications. Hex keys, also known as Allen wrenches, are essential hand tools for driving socket-head cap screws and set screws commonly found in HVAC equipment, plumbing fixtures, electrical enclosures, and pool equipment hardware. The WS-45 ships as a single unit and weighs 0.181 pounds, making it a compact addition to a service technician's toolkit. This set is suited for both installation work and field service tasks where hex fasteners are frequently encountered.
The WS-45 hex key set is appropriate for use in residential and light commercial service environments. Technicians across HVAC, plumbing, and electrical trades encounter hex fasteners during equipment installation, preventive maintenance, and component replacement. The 8-piece configuration provides a range of key sizes to address the variety of fastener dimensions typically found in trade equipment. This set is sold individually and is well suited for keeping in a service van or job-site toolbox.
Designed for general use with standard hex fasteners found across HVAC, plumbing, electrical, and pool equipment applications.
Hex key sets are hand tools and do not require installation. When using hex keys on equipment, always power down or shut off the system before accessing internal fasteners. Follow applicable trade codes and manufacturer service instructions when disassembling equipment components. Inspect keys for wear or rounding before use to avoid fastener damage.
