SATA GL42203 Double Box End Wrench 11 x 13mm

The 40° offset helps you reach fasteners that sit in recessed or tight spaces, while the off-corner loading design reduces the risk of rounding and improves grip on varied fasteners.

It is made from chrome-vanadium steel and finished with a corrosion-resistant chrome coating to extend tool life and resist rust.

Ideal for automotive, motorcycle, bicycle, machinery, and general maintenance tasks where you need access to 11 mm and 13 mm fasteners in tight spaces.

Choose the appropriate end for the fastener, fully seat the end, and apply steady turning force. Use the correct size to minimize slippage and avoid applying torque beyond the fastener's capability.

You get two common sizes in one tool, which saves space and swapping time. It does not have a ratcheting mechanism, so you rotate the wrench around the fastener rather than using a ratchet.

Wipe clean after use, dry thoroughly, and lightly oil the metal surfaces to prevent rust. Store in a dry toolbox or rack and avoid dropping or striking hard surfaces.

Off-corner loading helps reduce rounding, but always use the correct size and proper technique. If a fastener is severely corroded or damaged, consider applying penetrating oil and using appropriate methods.

Yes. It combines two sizes into one compact tool, saving space and typically offering a cost advantage over purchasing two individual wrenches while staying versatile.
