DIN6330 High Hexagon Nuts

DIN 6330 High Hex Nuts are designed with an increased nut height compared with standard hexagon nuts, providing a longer threaded section for bolted connections. The additional height allows more threads to engage with the mating bolt or threaded rod, making the nut useful where greater thread engagement or a longer clamping section is required.

The hexagonal external profile provides conventional wrench access for tightening and removal, while the increased height gives the nut a different dimensional profile from standard-height hex nuts such as DIN 934. This makes DIN 6330 a practical option when the available thread length, assembly geometry, or required engagement calls for a taller nut. DIN 6330 High Hex Nuts can be used with threaded rods, bolts, studs, machinery components, fixtures, equipment assemblies, and fabricated structures. Different material and surface-finish options can be specified according to the mechanical requirements and operating environment.

Specification:

DIN 6330 High Hex Nuts are specified by their metric internal thread, nut height, across-flats dimension, and material or property class. The increased nut height is part of the dimensional design and provides a longer threaded section than a standard-height hex nut. The nut is available in different steel grades and surface finishes according to the required application. Carbon steel versions can be supplied with protective coatings, while stainless steel options are available for assemblies where the material itself provides increased corrosion resistance.

Dimension Chart of DIN6330 High Hexagon Nuts:

The DIN 6330 dimension chart provides the key measurements required to identify and match the high hex nut with the corresponding bolt or threaded rod. In addition to the nominal thread diameter, the chart covers the nut height and across-flats dimension, which define the overall installation space and wrench access. The increased nut height is an important dimensional feature of DIN 6330. When compared with a standard-height hex nut, the additional axial length provides a longer threaded section while maintaining the familiar six-sided profile. Customers should check the thread size, pitch, nut height, and width across flats against the mating fastener and available assembly space before ordering.
