Lang ROWM-1517M Box End Offset Wrench 15x17mm 12pt

Product Description

The LANG ROWM-1517M is a ratcheting offset box end wrench designed for professional fastener work in tight or awkward clearances. It features dual-size box ends at 15 mm and 17 mm, a 12-point drive pattern for greater contact on hex fasteners, and a 25-degree head offset angle that provides knuckle clearance and swing arc in confined spaces. The chrome-plated steel construction resists corrosion and handles daily shop use. Both ratcheting and reversing functions are built in, eliminating the need to remove and reposition the wrench on each stroke. Mechanics, plumbers, pipefitters, and HVAC technicians will find this tool useful in engine bays, mechanical rooms, and equipment installations where open-end wrenches lack the grip and socket drives lack the access.

This wrench is suited for residential and commercial maintenance environments where 15 mm and 17 mm metric fasteners appear regularly. Typical applications include servicing HVAC equipment, plumbing fixture hardware, mechanical assemblies, and general industrial maintenance. The ratcheting mechanism reduces fatigue and speeds up repetitive fastener work in areas with limited swing. The offset head angle allows the handle to clear obstructions while keeping the box end seated on the fastener, making it practical for under-panel and in-cabinet service work.

Key Features

• Dual-size box ends: 15 mm and 17 mm
• 12-point drive pattern for increased fastener contact and reduced slip
• 25-degree head offset angle for knuckle clearance in confined spaces
• Built-in ratcheting and reversing action for faster single-position operation
• Chrome-plated steel construction for corrosion resistance and durability

Compatibility

Designed for use with standard metric hex fasteners at 15 mm and 17 mm across flats, compatible with typical 12-point box end wrench applications in trade and industrial maintenance settings.

Installation Notes

This wrench is a hand tool intended for use by mechanics, HVAC technicians, plumbers, and other trade professionals. Ensure the box end is fully seated on the fastener before applying torque to avoid rounding. Verify the reversing mechanism is set to the correct drive direction before beginning work. Wipe clean after use and store dry to maintain the chrome finish.
