TECHNICAL DATA

REGULATIONS

The DIN 3126 and ISO 1173 standards are international standards that specify the characteristics of couplings and screwdriver bits for use in electric or manual tools. ISO 1173 defines the most common types of external hexagonal couplings (such as C 6.3, E 6.3, H 6.3) used to insert bits into bit holders or directly into electric screwdrivers, ensuring their global compatibility and interchangeability. Meanwhile, DIN 3126 complements this standard by establishing the requirements for screwdriver bits and their holders, covering aspects such as the dimensions of the working tip (e.g., Phillips, Pozidriv, Torx), material hardness, and torsional strength. Together, these standards ensure that the bits fit securely, transmit torque efficiently, and have an adequate lifespan, improving safety and productivity in screwing tasks.

USES AND APPLICATIONS

Torque application: It is used to tighten and loosen hexagonal or bi-hexagonal nuts and bolts. The 1/2" drive is a standard and robust size, commonly used in jobs that require moderate to high force (torque).

AF Measurement System (Inches): This set is specifically for fasteners measured in the imperial system (AF - Across Flats, or in inches). It is essential for working on:

American Vehicles: Many cars and trucks manufactured in the U.S. (both classic and some modern) use fasteners in inches.

Motorcycles: Brands like Harley-Davidson predominantly use imperial measurements.

Industrial and Agricultural Machinery: Certain types of machinery, especially those of American origin, use this system.

Aerospace: It is common in aircraft maintenance.
