Flat Spanner MEGA 20 x 22 mm model 34450

The MEGA Flat Spanner 20 x 22 mm model 34450 is a double open-ended wrench designed for manual tightening and loosening of hexagonal nuts and bolts in two adjacent sizes. Manufactured for general workshop and maintenance use, this flat spanner delivers a fixed jaw profile on each end to ensure a secure grip and efficient torque transfer during hand-operated tasks. Its compact flat design allows access in narrow spaces and stable handling for mechanical, plumbing and assembly operations.

Advantages

The flat spanner provides two commonly used metric sizes in a single tool, reducing the need to switch wrenches when working on fasteners of 20 mm and 22 mm. Its open-ended jaws permit quick engagement and removal of nuts and bolts on threaded studs and fittings. The flat profile improves reach into confined areas and keeps the tool lightweight and easy to position. Durable material and a precision-cut jaw geometry support consistent contact and minimize rounding of fastener corners when used with appropriate hand force.

Suitable for

• Automotive repair and maintenance where adjacent wrench sizes are required
• Plumbing work on fittings and couplings with 20 mm and 22 mm hex fasteners
• General assembly and disassembly tasks in workshops and maintenance departments
• On-site maintenance where a compact, flat wrench is advantageous

Key specifications

• Wrench type: double open-ended (flat spanner)
• Sizes: 20 mm and 22 mm open ends
• Material: hardened steel construction for manual use
• Finish: corrosion-resistant surface treatment
• Design: slim, flat body for access in tight spaces

How to use

Select the end that matches the fastener size (20 mm or 22 mm) and place the open jaw fully over the nut or bolt head so the flats of the fastener sit squarely in the wrench jaws. Apply steady hand force perpendicular to the fastener axis to tighten or loosen; avoid excessive impact or use with cheater bars. If access is limited, position the flat body to reach around nearby components and use controlled strokes to avoid slipping. After use, wipe clean and store in a tool rack or pouch to prevent corrosion.

Usage recommendations

Use the MEGA 20 x 22 mm flat spanner for manual tightening and loosening only. Do not use with power tools or as a hammer. Match the correct jaw size to the fastener and apply force evenly to reduce the risk of rounding. Regularly inspect the jaws for wear and maintain a clean, dry finish to prolong tool life.
