The WILLIAMS COMFORT PRODUCTS HK-6mm is an L-type hex key sized at 6 millimeters, sold in a bag of 10. L-type hex keys are standard hand tools used across HVAC, plumbing, electrical, and general mechanical service work. The L-shape provides two drive lengths: the short leg for confined spaces and the long leg for added torque. This key is a practical addition to any service technician's toolkit where 6mm fasteners are commonly encountered.
This hex key is suited for residential and light commercial service applications. Technicians use 6mm hex keys when servicing equipment covers, access panels, fan assemblies, pump housings, and other mechanical components that use metric socket-head fasteners. The 10-per-bag quantity makes it easy to stock a supply for field use or shop inventory.
Designed for use with 6mm metric hex socket fasteners commonly found in HVAC, plumbing, and mechanical equipment assemblies.
No power disconnection is required for general fastener driving with hand tools, but always follow lockout/tagout procedures when servicing energized or pressurized equipment. Use the long leg of the L-key for initial engagement and higher torque, and the short leg for access in tight spaces. Inspect the hex key for wear or rounding before use to avoid fastener damage.
