DEEP OFFSET DOUBLE BOX END WRENCH20 X 22 MM ST42309 SATA

One end is 20 mm and the other end is 22 mm.

The deep offset increases clearance between the bolt head and adjacent components, allowing you to reach fasteners that sit in tight or crowded spaces.

It is typically made from high-strength alloy steel with a corrosion-resistant finish designed for durability in mechanical work. The exact spec is part of SATA’s standard tool finishes.

It's ideal for automotive, bicycle, motorcycle, and machinery maintenance where fasteners sit close to panels or frames, or where space is limited and a standard wrench can’t reach.

Align the wrench squarely with the bolt, apply steady torque, and avoid side loading or slipping. Use gradual, controlled movements and keep the wrench perpendicular to the fastener whenever possible.

Keep it clean and dry after use, wipe off any oils, and store it in a toolbox or rack to prevent corrosion and keep the ends protected.
