REGULATIONS

DIN 3113A-ISO 3318-ISO 7738

The DIN 3113 standard is the standard that defines the specifications for combination wrenches with fixed and angled star openings (or ring), which are widely used in mechanical applications. This standard establishes the dimensional requirements for the openings, ensuring that the nominal size of the wrench (e.g., 13 mm) accurately corresponds to the hexagonal or dodecagonal nut or screw. It also specifies the tolerances, material hardness, and torque resistance that the wrench must withstand, ensuring its durability and a secure grip without deforming or damaging the fastening element.

The DIN 838 / ISO 3318 standard is a technical standard that defines the dimensional and performance requirements for double angled star 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 screws, 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.
