Hook Wrench AWTools KLUCZ hinged 80–120 mm Black Line

The AWTools KLUCZ hinged hook wrench Black Line with an adjustable jaw capacity of 80–120 mm is a hand tool designed to grip and turn rounded collars, threaded rings and circular fittings. Its hinged joint provides improved access and allows the user to change the working angle, making it easier to reach fasteners in confined or awkward positions. The tool is intended for use in workshops, plumbing and general mechanical maintenance where a secure grip on circular fasteners is required.

Advantages

The hinged design allows angle adjustment for better access to recessed or hard-to-reach collar nuts. The adjustable jaw range covers a span from 80 to 120 mm, reducing the need for multiple fixed-size wrenches. A shaped hook profile provides secure contact with rounded edges, minimising slippage while turning. The Black Line finish increases surface durability and helps resist corrosion from workshop environments.

Suitable for

• Removing and tightening round or threaded collars and retaining rings
• Plumbing work on pipes and fittings with circular fasteners
• Workshop and mechanical maintenance where space is limited or access angles vary
• Servicing pumps, gearboxes and machinery with external collar nuts

Key specifications

• Adjustable jaw capacity: 80–120 mm
• Hinged joint for angle adjustment
• Hook-style gripping profile for rounded fasteners
• Black protective finish for increased corrosion resistance
• Single-handed operation with manual torque application

How to use

Select the jaw opening to correspond with the diameter of the circular fastener, position the hook profile securely against the fastener edge and set the hinged joint to an angle that gives clear access. Apply steady manual torque in the required direction, keeping the tool aligned with the fastener to avoid slipping. For stubborn or corroded fasteners, apply penetrating lubricant and allow time to work before attempting to turn. Inspect the gripping surfaces of the wrench before use to ensure they are clean and undamaged.

Usage recommendations

Use appropriate personal protective equipment, such as gloves and eye protection. Do not use the wrench as a hammer or for prying; avoid exceeding safe manual torque to prevent tool or fastener damage. Store the tool in a dry place to maintain the Black Line finish and check the hinge periodically for smooth operation.
