SATA GL42224 Double Box End Wrench 13 x 16mm

The ends are 13 mm and 16 mm. Having two sizes in one tool allows you to tackle two common fastener sizes without switching wrenches, saving time and reducing tool clutter in cramped workspaces.

Key features include a 40° offset between the two box ends for better access, off-corner loading on the box ends to improve grip and reduce rounding, a slim head for reaching tight spots, and laser-etched size markings for quick identification.

The wrench is crafted from high-quality steel and finished with a chrome-plated coating. This combination provides strength, corrosion resistance, and longer tool life in tough conditions.

It's ideal for automotive work, machinery maintenance, bicycle repairs, and any scenario where you need to reach recessed fasteners or work in tight spaces with two common metric sizes in one tool.

Seat the appropriate end squarely on the fastener, apply steady torque, and avoid using the wrench as a lever or for prying. Use one end for initial loosening and the other end for final tightening, ensuring the fastener remains properly engaged to prevent rounding.

Wipe it after use to remove grime, dry thoroughly, and apply a light coating of oil to prevent rust. Store in a dry toolbox or rack, and inspect for signs of wear or deformation before each use.

This wrench is designed for direct turning on hex fasteners. For controlled torque, pair it with a torque wrench compatible with box-end sockets or use a traditional ratchet and appropriate socket set where applicable, ensuring proper engagement on the fastener.

Ensure the fastener is properly seated before applying force, wear safety glasses for particle protection, and maintain a firm grip to prevent slipping. Use the correct size end to avoid rounding and avoid striking the wrench with heavy impacts or using it as a pry bar.
