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 fasteners in construction and engineering environments.

REGULATIONS

DIN ISO 1711-1 (Mounting tools for screws and nuts - Hand wrenches - Part 1: Open-end and combination wrenches - Technical requirements)

The DIN ISO 1711-1 standard establishes the technical and performance requirements for hand wrenches used in the assembly of screws and nuts, specifically covering fixed open-end wrenches, star (ring) wrenches, and combination wrenches. It defines criteria for material hardness, torsion resistance under specific loads, and tolerances in the openings of the jaws, ensuring a proper fit to the fastening element and minimizing the risk of tool deformation or rounding of the nut or screw during use.

DIN 3113A (Metric open-end and combination wrenches - With angled jaws)

The DIN 3113A standard specifically focuses on metric combination wrenches that have a fixed jaw on one side and an angled star (ring) jaw on the other. This specification details the precise dimensions of both jaws (the fixed and the angled), the angle of the ring (generally 15° to facilitate access to fasteners in tight spaces), and the nominal length of the wrench. The "A" in the designation refers to this particular design of combination wrench with the angled star jaw. By complying with DIN 3113A, it is ensured that the wrench will have the correct measurements to work with metric screws and nuts, in addition to providing the expected functionality and ergonomics to reach hard-to-access areas.
