Key Features of DIN 933 Bolts

All specifications comply with DIN 933 standard issued by DIN Deutsches Institut für Normung.

DIN 933 specifies hexagon head bolts with full threading, designed for general-purpose fastening applications that require a strong, durable connection. These bolts are known for their high mechanical strength and are widely used in construction, machinery, automotive, and engineering sectors.

With a standard hex head and a fully threaded shank, DIN 933 bolts allow for secure clamping across a wide range of materials and are especially suitable for assemblies requiring precise alignment and tight fastening.

Manufactured to DIN (Deutsches Institut für Normung) standards, they ensure dimensional consistency, interchangeability, and compatibility with international equivalents such as ISO 4017.

DIN 933 bolts are manufactured with full threading, providing maximum thread engagement and tensile strength. They conform to strict dimensional tolerances set by the DIN standard, making them ideal for high-precision applications.
