Williams Comfort Products HK-12mm L-type Hex Key 12mm

Product Description

The WILLIAMS COMFORT PRODUCTS HK-12mm is an L-type hex key sized at 12mm, sold in a bag of 25 pieces. L-type hex keys deliver straight-arm leverage on one side and a shorter ball-end or stub side for access in tight spaces. This is a hand tool used by HVAC technicians, plumbers, electricians, and general trade professionals when driving or loosening socket-head fasteners during equipment installation and service. The 25-piece bag format makes it practical for stocking a service vehicle or shop bench.

This hex key is suited for general trade work wherever 12mm socket-head cap screws or set screws are encountered. Common applications include equipment panel fasteners, pump assemblies, motor mounts, and mechanical connections found in HVAC, plumbing, and light industrial service work. The bag quantity supports tool crib restocking or crew supply needs.

Key Features

Compatibility

Designed as a standard metric L-type hex key for use with 12mm socket-head cap screws and set screws across HVAC, plumbing, and general mechanical service applications.

Installation Notes

No power isolation is required for hand tool use, but always de-energize and lock out equipment before working on fasteners near electrical or pressurized components. Ensure the correct key size is seated fully in the fastener socket before applying torque to prevent rounding. L-type hex keys are a hand-tool application and do not require specialized trade licensing to use.
