DIN 7967 Hot-dip galvanized Spring-loaded lock nut

Overview

DIN 7967 is a spring-loaded lock nut with an internal metric thread, designed to prevent self-loosening. Its unique design features internal petals that, when installed, fit snugly against the thread of a bolt or screw, ensuring a secure hold. The operating principle of this spring-loaded lock nut is based on creating resistance to unscrewing thanks to the petals inside the nut and the notches at the tops of the hexagon. The nut is installed by hand on a metric fastener: it is slipped onto the bolt, causing the internal petals to flip in the opposite direction, becoming spring-loaded and bearing against the threads. At the same time, under the pressure applied during installation, the faces of the nut, bearing against the component, spread apart slightly due to the notches at the vertices, thereby creating additional spreading stress between the component and the internal petals.

The nut is made of steel and has a hot-dip galvanized coating, which provides additional protection against corrosion.

Applications

The DIN 7967 spring-loaded lock nut is made of steel with a hot-dip galvanized coating, which ensures high corrosion resistance and durability. It is designed for use in assemblies where it is important to prevent loosening due to vibrations or dynamic loads. Thanks to its design, the nut effectively secures the joint, making it an ideal choice for mechanisms where access to tools is limited.

This nut can be used on its own or in combination with other fasteners, which increases the reliability of the connection. It meets strength standards, ensuring stable performance under various loads. The nut’s dimensions comply with international standards, making it versatile for use in various industries.

Technical Specifications

Equivalents
The DIN 7967 spring-loaded lock nut is made of hot-dip galvanized steel, which provides it with high corrosion resistance. It is designed to prevent connections from loosening on their own, thanks to a special spring mechanism. When selecting alternatives, it is important to consider the diameter, thread pitch, and nut height, as standard nuts, such as DIN 934, do not provide the necessary locking effect.

Is It Worth Buying?
The DIN 7967 spring-loaded lock nut is the ideal solution for ensuring the reliability of threaded connections. Its spring-loaded design prevents accidental loosening, making it indispensable in vibrating environments. The zinc coating provides effective corrosion protection, extending the product’s service life.

This nut is available in various sizes, making it easy to match standard bolts and screws. The material’s high strength meets Class 8 requirements, ensuring reliability in a wide range of applications, from automotive to industrial.

Applications
The DIN 7967 spring-loaded lock nut is an indispensable component in many industries, particularly in mechanical engineering and the automotive industry. It ensures a secure connection under vibrating conditions, preventing the nut from loosening on its own.

When selecting a nut, it is important to pay attention to its dimensions, specifically the diameter, thread pitch, and height. The nut is made of hot-dip galvanized steel, which provides additional protection against corrosion. Make sure the selected nut meets the requirements of your project and is compatible with other fasteners.
