Box End Wrench Offset 8×9 mm MEGA 36538 bent double-ended spanner

MEGA 36538 is an offset box end wrench with 8×9 mm box heads on both ends designed for working in confined or recessed spaces. The bent double-ended spanner lets you approach nuts and bolts from different angles, improving access where a straight wrench would not fit. It is intended for tightening and loosening metric fasteners in automotive, mechanical and general repair tasks.

Advantages

The offset, bent design provides clearance over obstructions and enables torque application from alternative positions without disturbing nearby components. Dual 8 mm and 9 mm box ends on a single tool reduce the need to switch wrenches when working with adjacent fasteners of similar sizes. The closed box ends fully surround the fastener head for secure engagement and reduced risk of rounding.

Suitable for

• Automotive repair and maintenance where space is limited
• Bicycle and small machinery adjustments with metric fasteners
• General household and workshop tasks requiring 8 mm or 9 mm box ends

Key specifications

• Tool type: offset double-ended box wrench
• Box head sizes: 8 mm and 9 mm
• Head style: bent/offset for improved clearance
• Ends: closed box ends for full engagement
• Use case: manual tightening and loosening of metric nuts and bolts

How to use

Select the correct end for the fastener size (8 mm or 9 mm) and position the box end fully over the nut or bolt head. Apply steady force to the handle, using the offset to clear nearby parts and achieve a comfortable grip. For initial loosening, use controlled force to avoid slipping; once loosened, you can reposition the wrench for additional leverage. After use, wipe the tool clean and store it in a toolbox or on a wrench rack to prevent corrosion.

Usage recommendations

Use the 8×9 mm offset box wrench where straight wrenches cannot reach and avoid using excessive force that could damage the fastener or the tool. Inspect the box ends periodically for wear and replace the tool if the engagement becomes loose.
