SATA ST08004SJ 8-Piece Metric Double Box End Wrench Set

The double box ends provide a secure grip on fasteners from both sides, reducing the risk of rounding and allowing for better torque transfer in tight or recessed areas.

The 40° offset improves accessibility to recessed or hard-to-reach fasteners, allowing you to apply torque in spots where straight wrenches can’t reach easily.

They are made from chrome vanadium steel and finished with a bright, full-polish chrome plating that resists corrosion and wipes clean easily.

Each wrench is clearly stamped with its size in metric units, and the high-visibility markings make size identification fast and straightforward.

It’s well-suited for automotive, plumbing, and general repair applications where metric fasteners are used.

The set comes with a storage case for organized storage and easy transport, keeping your workspace tidy and your wrenches protected.

Wipe the wrenches clean after use, keep them dry, and apply a light coating of oil to prevent rust. Store in the provided case to minimize exposure to moisture and dust.

Yes. Use the correctly sized wrench for the bolt, apply steady, even torque, avoid using cheater bars, and wear eye protection in work environments where debris could become airborne.
