TECHNICAL DATA

USES AND APPLICATIONS

General Mechanics and Automotive: For tightening and loosening metric nuts and bolts in engines, chassis, transmissions, and auxiliary equipment.

Industrial Maintenance: Adjusting and repairing machinery, pumps, and pipes, using the 15° angle of the star side to access fasteners in confined spaces.

Installation and Assembly Work: Used by technicians to assemble structures, shelves, and equipment that use metric hexagonal screws in construction and engineering environments.

REGULATIONS

The DIN 3113 standard is the specification that defines the requirements for combination wrenches with fixed and angled star (or ring) openings, 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 bolt. It also specifies the tolerances, material hardness, and torsion resistance that the wrench must withstand, ensuring its durability and a secure grip without deforming or damaging the fastening element.
