Dimension of DIN934 Hex Nuts

DIN934 is a standard for hex nuts used in metric applications. The dimension of DIN934 hex nuts depend on the specific size and class of nut you are referring to. Here are some general dimensions for DIN 934 hex nuts:

1. Thread Size (Nominal Diameter): This is the size of the screw or bolt that the hex nut is designed to fit. For example, M6, M8, M10, M12, etc. The “M” stands for metric.

2. Across Flats (AF) or Wrench Size: The distance across the flat sides of the hexagonal shape. This dimension corresponds to the size of the wrench or socket needed to tighten or loosen the nut. For example, an M6 DIN 934 hex nut typically has an AF of 10mm, while an M12 hex nut has an AF of 19mm.

3. Height (Thickness): The thickness or height of the hex nut can vary depending on the class or type of nut. For example, a standard hex nut may have a height that is roughly 0.8 times the nominal diameter.

4. Pitch: This specifies the distance between threads. It is related to the thread size and is used to determine the height of the nut.
