What Are DIN 933 Hexagon Head Bolts?

DIN 933 refers to a standard for hexagon head bolts with a fully threaded shank. DIN stands for “Deutsches Institut für Normung,” which translates to the German Institute for Standardization. This institute develops norms and standards as a service to industry, the state, and society, and it is recognized as a significant standard-setting organization worldwide.

As a reliable fastener supplier, Xinchi is glad to introduce the key characteristics of DIN 933 hexagon head bolts.

Fully Threaded: Unlike some bolts that have a shank without threads, DIN 933 bolts are fully threaded from under the head to the tip. This design allows the bolts to be threaded entirely through a nut or tapped hole.

Hexagonal Head: These bolts feature a six-sided hexagonal head used with tools like wrenches or sockets. This shape allows for easier driving and higher torque transfer during installation and tightening.

Standardized Dimensions: As with all DIN standards, DIN 933 bolts have standardized dimensions including the diameter, thread pitch, and length. This standardization ensures compatibility and interchangeability across applications and industries.

Material and Coating: DIN 933 bolts can be made from various types of materials such as carbon steel, stainless steel, or alloy steel. They can also have different types of coatings or finishes to resist corrosion, such as zinc plating or galvanizing.

Usage: These bolts are used in a wide range of applications, from construction and machinery to automotive and electronics, where a fully threaded bolt is needed.

Metric Sizes: DIN 933 specifies metric dimensions, and the bolts are used in systems where metric measurements are standard.

The DIN 933 specification ensures that products conform to certain minimum standards of quality and are compatible with other components and equipment, simplifying the design, manufacturing, and procurement processes.
