The quality of fasteners plays an important role in the construction, repair, installation, and manufacturing sectors. To date, mankind has invented a huge number of connecting elements of various types and purposes. DIN 6334 nuts are especially popular.
What are the application features of fasteners DIN 6334
In consumer reviews, you can often see that this or that master is in a specialized online store. Indeed, reduced prices are set for these fasteners, especially for wholesale buyers. Its main purpose is to connect threaded studs or their elements. Such nuts are called elongated, transitional, extending.
It is known that the initial size of threaded studs, as a rule, is 1000 or 2000 mm.During installation, parts of the required length are cut off from them. Before this, connecting hardware is wound, which have a similar thread and the same strength parameters. Without fail, defects in the form of burrs are eliminated and chamfers are removed. After twisting the nut, a finished stud is obtained.
Fasteners are made of steel. This material is prone to corrosion after cutting. Therefore, the ends must be treated with organic-based paints, zinc, grease. Before completing the work, you must make sure that the studs are connected in the fastener exactly in the center. If additional protection against dynamic loads that cause self-loosening is required, lock nuts must also be used.
Types and areas of use
Nuts DIN 6334 are available in strength classes 8 or 10. The main steel grades used in production are carbon galvanized A2, A4. The size range in terms of internal thread diameter and length is quite extensive. The most widely used sizes are M10-M36.
DIN 6334 nuts are used:
- when installing ventilation ducts;
- installation of fire extinguishing systems;
- fixing suspended elements of metal and other structures;
- installation of heating equipment;
- various construction works;
- interior and exterior decoration of buildings.
The sleeve nut is excellent for converting rotational actions into translational actions in mechanisms that do not experience external loads. The fastener has a hexagonal shape. To install it, an open-end wrench is used.
