Open End Wrench Wera 05020264001

The Wera 05020264001 open end wrench is a single-piece tool finished in chrome to resist corrosion and provide a smooth surface for handling. Sized for 30 mm and 32 mm fasteners and measuring 305 mm in length, this wrench is built to deliver precise engagement and effective torque transfer for a range of mechanical tasks. Its open ends are shaped to fit close to flat surfaces and allow operation where a ring or socket cannot be used.

Advantages

The chrome finish offers long-term corrosion resistance and easy cleaning after use. A one-piece design increases strength and reduces the risk of joint failure under load. The specified 305 mm length balances leverage and access in confined spaces, while the dual-size heads (30 mm and 32 mm) reduce the need to change tools for adjacent fasteners. The wrench’s geometry promotes secure engagement and minimizes rounding of bolt heads when used correctly.

Suitable for

• Tightening and loosening 30 mm and 32 mm nuts and bolts
• Automotive maintenance where access is limited
• Industrial machinery assemblies and repairs
• Construction and heavy equipment fastening
• Workshop and professional mechanic toolsets

Key specifications

• Tool type: Open end wrench, single piece
• Head sizes: 30 mm and 32 mm
• Overall length: 305 mm
• Finish: Chrome plated for corrosion resistance
• Material: High-strength alloy steel (hardened and tempered)
• Design: Fixed open jaws for direct grip and torque transfer

How to use

Position the appropriate open end over the nut or bolt so the wrench fully seats on the flats. Apply steady force to the handle, keeping the wrench aligned with the fastener to avoid slipping. For loosening tight fasteners, use controlled, incremental pressure rather than sudden jerks. When access is limited, use the 305 mm length for leverage while ensuring clearance for safe movement. Inspect contact surfaces before use and avoid side loading that can damage the fastener or tool.

Usage recommendations

Use the wrench within its size range (30 mm and 32 mm). Do not use cheater bars or apply impacts with a hammer; such actions can overstress the tool and create safety hazards. Store the wrench in a dry place and clean after use to preserve the chrome finish and prevent corrosion.
