TECHNICAL DATA

REGULATIONS

The DIN 838 / ISO 3318 standard is a technical standard that defines the dimensional and performance requirements for offset double hexagon wrenches. The DIN 838 standard is the German designation (Deutsches Institut für Normung), while ISO 3318 is its international equivalent. The regulation ensures that the wrenches are manufactured with precise dimensions for fitting hexagonal or square nuts and bolts, and establishes the maximum torque requirements that the wrench must withstand without deformation or breakage, which is essential for professional and heavy use in mechanics and industry.
