DIN 1479 Hex Nut

DIN 1479 is a German Industrial Standard (Deutsches Institut für Normung) that specifies the dimensions and characteristics of hex nuts with left-hand threads. Hex nuts are six-sided nuts widely used to fasten bolts and screws in various applications.

DIN 1479 hex nuts are specifically designed with left-hand threads, which means they are turned counterclockwise to tighten, unlike the more common right-hand threaded nuts that are turned clockwise to tighten. Left-hand threaded nuts are used in specific applications where counterclockwise rotation is required for assembly or where the design demands a left-hand fastening mechanism.

Key features and characteristics of DIN 1479 hex nuts include:

1. Left-Hand Threads: DIN 1479 hex nuts have left-hand internal threads that match with left-hand threaded bolts or screws.

2. Hexagonal Shape: Like standard hex nuts, DIN 1479 hex nuts have six flat sides (hexagonal shape), which allows for easy tightening and loosening with a wrench or pliers.

3. Material: DIN 1479 hex nuts can be made from various materials, including steel, stainless steel, brass, and other metals, depending on the application requirements.

4. Thread Specifications: The left-hand internal threads of DIN 1479 hex nuts follow specific thread specifications, such as metric or unified threads.

5. Application: DIN 1479 hex nuts with left-hand threads are used in specific applications where left-hand fastening is necessary or advantageous. Some applications include specialized machinery, mechanical linkages, and certain rotational mechanisms.

It's important to note that DIN standards have been replaced by ISO (International Organization for Standardization) standards in many cases, and DIN 1479 hex nuts have been included in the ISO standard as ISO 4035. The specifications and dimensions of ISO 4035 hex nuts with left-hand threads are essentially the same as those of the original DIN 1479 standard.

When using DIN 1479 (or ISO 4035) hex nuts with left-hand threads, it is essential to ensure that the corresponding left-hand threaded bolts or screws are also used to achieve proper and secure fastening. It's always recommended to follow the appropriate standards and guidelines when selecting and using fasteners to ensure safety and reliability in different applications.
