Williams Comfort Products HK-3mm L-type Hex Key 3mm

Product Description

The WILLIAMS COMFORT PRODUCTS HK-3mm is an L-type hex key sized at 3 millimeters, sold in bags of 25 individual keys. L-type hex keys are a standard hand tool for trade professionals who need to drive socket head cap screws, set screws, and similar fasteners encountered during HVAC equipment assembly, plumbing fixture installation, and electrical panel work. The L-shape design provides two usable ends: the short arm for torque and the long arm for reach and speed. These keys are a utility item kept on service vans and in tool kits across multiple trades.

The HK-3mm is suited for general trade service work where a 3 mm hex drive is required. The bag-of-25 format makes this a practical choice for shop stocking, fleet van replenishment, or job-site kitting where individual keys are prone to loss. Both HVAC technicians and plumbers regularly encounter 3 mm fasteners on equipment panels, valve packing nuts, and component mounting hardware.

Key Features

• L-type profile provides both torque leverage on the short arm and extended reach on the long arm
• 3 mm hex drive size covers common fasteners found on HVAC, plumbing, and electrical equipment
• Sold in a 25-count bag for efficient stocking and van inventory management
• Compact individual weight supports lightweight tool kit organization

Compatibility

Designed for use with standard 3 mm socket head cap screws and set screws across residential and light commercial trade applications.

Installation Notes

Hex keys are a hand tool requiring no power source or code-specific installation procedure. Select the correct 3 mm key before applying torque to avoid rounding fastener sockets. Do not use extension bars or pipes to increase leverage on L-type hex keys, as this can damage the fastener or the key. Replace any key that shows visible wear or deformation at the tip.
