Review
Din 6334 is called a connecting nut or adapter nut, which defines the essence of the application of this nut. It acts as a coupling for fasteners with a metric thread, but looks like an elongated hexagonal nut. It is installed with a hexagon wrench.
Strength class DIN 6334
DIN 6334 nuts are made of high-strength alloy steel with strength class 10.
DIN 6334 fastening group
Depending on the material of manufacture, DIN 6334 is classified into a group:
- High-strength fasteners
- Stainless steel fasteners
Materials of manufacture:
- Steel, which can be additionally coated with zinc and zinc plating.
- Stainless steel, steel grades A2 and A4. This material does not require any additional treatments.
How to install the DIN 6334 connecting nut
DIN 6334 connecting nuts are used in conjunction with studs to extend elements in engineering structures.
Using an Allen key, the nut is screwed halfway onto the stud, and another stud is screwed onto the other side. For greater connection reliability, additional nuts can be used by tightening the coupling on both sides.
Areas of application for the DIN 6334 coupling nut
DIN 6334 is used in ventilation suspension and plumbing structures. This nut is also common in construction for the installation of piping systems or the construction of structures for room-entry systems for suspended elements.
The range of applications for the nut also directly depends on the material of manufacture and the coating of the product:
- High-strength structural alloy steel. The high strength class of 10 allows the nuts to be used for highly loaded connections.
- Zinc, which can be additionally coated with steel, protects against corrosion if the fasteners are to be used in aggressive environments.
- Stainless steel makes it possible to use the fasteners at significant temperature changes and in aggressive and humid environments.
