Open-end wrench STANLEY 4-87-103, 20x22 mm, 237 mm length, silver

STANLEY 4-87-103 open-end wrench with fixed 20x22 mm jaws and a 237 mm overall length is a hand tool designed for gripping and turning bolts and nuts of the specified sizes. The tool has a metal silver finish and two open ends sized 20 mm and 22 mm. Its length provides leverage for higher torque while keeping the tool compact enough for many mechanical, plumbing and assembly tasks.

Advantages

The open-end wrench offers a solid metal construction and a precisely machined jaw profile for secure contact with fasteners, reducing the risk of rounding. With two commonly used metric sizes on a single tool, it removes the need to switch between wrenches frequently. The tool's 237 mm length balances reach and control, enabling efficient application of torque in confined and open working spaces.

Suitable for

• Automotive and mechanical repairs involving 20 mm and 22 mm nuts or bolts
• Plumbing assemblies and fittings where open-end access is required
• General assembly and maintenance tasks in workshops and industrial environments

Key specifications

• Jaw sizes: 20 mm and 22 mm
• Overall length: 237 mm
• Finish: metal silver
• Type: open-end wrench with two fixed ends
• Material: steel construction (metal)

How to use

Select the correct end (20 mm or 22 mm) that matches the fastener size, place the open jaws fully onto the nut or bolt head, and apply steady force in the required direction to tighten or loosen. Position the wrench so the load is applied on the flats of the fastener for secure contact and to minimize slippage. For increased torque, use the full length of the handle while maintaining stable hand placement and avoid sudden impacts or excessive force.

Usage recommendations

Inspect the jaws before use to ensure they are free of burrs or deformation. Use appropriate hand protection as needed and avoid using the wrench with extensions or cheater bars that exceed the intended leverage. Store the wrench in a dry place to reduce corrosion and maintain precise jaw contact.
