Product Description

Product Description

DIN 6331 Hexagon Collar Nut 

The DIN 6331 Hexagon Collar Nut is a standardized hexagonal collar nut that falls within the DIN 6331 specification. It features a large, flat washer (collar) on the outside of the nut, typically used to increase the contact area and distribute pressure, preventing the nut from loosening during application. The collar design helps improve installation stability and provides additional support, making it particularly suitable for applications requiring high stability. These nuts are commonly used to connect and secure two objects, particularly in applications subject to high forces or where loosening due to vibration needs to be prevented.

Applications

Building Insulation: Primarily used in the installation of thermal insulation systems in residential, commercial, and industrial buildings.
External Wall Insulation: Often used in External Thermal Insulation Composite Systems (ETICS) to fix insulation boards to external walls.
Roof Insulation: Suitable for securing insulation materials on roofs to enhance energy efficiency and thermal performance.
Floor Insulation: Utilized in floor insulation systems to prevent heat loss through the flooring and improve overall energy efficiency.
