Nut DIN 7967 M48 zinc

Overview

DIN 7967 is a zinc-plated spring lock nut with an internal metric thread, designed to prevent self-loosening. Its design includes internal tabs that press tightly against the thread of a bolt or screw during installation, providing secure locking.

The operating principle of this spring lock nut is based on creating resistance to loosening through the internal tabs and the slots in the corners of the hexagon. The nut is installed manually onto a metric fastener: it is placed onto the bolt, and the internal tabs turn in the opposite direction, becoming spring-loaded and pressing against the thread. At the same time, under installation pressure, the nut faces slightly spread apart due to the slots in the corners, creating additional expansion stress between the part and the internal tabs.

The nut is made of steel and has a zinc coating that provides additional corrosion protection.

Applications

The DIN 7967 spring lock nut is made of zinc-plated steel, providing additional corrosion protection and improved product durability. It is designed for connections where it is important to prevent loosening under vibration or dynamic loads. Thanks to its design, the nut effectively locks the connection, making it a good choice for mechanisms where tool access is limited.

This nut can be used as an independent fastening element or in combination with other fasteners to improve connection reliability. The nut dimensions comply with standard requirements, making it convenient for use in various industrial and technical applications.

Technical Specifications

Equivalent Standards

The DIN 7967 spring lock nut is made of zinc-plated steel, providing additional corrosion protection. It is designed to prevent self-loosening of connections thanks to its special spring-locking design.

When selecting equivalents, it is important to consider the thread diameter, thread pitch, nut height, material, and coating type. Standard hex nuts, such as DIN 934, do not provide the required locking effect and are not direct replacements.

Is It Worth Buying?

The DIN 7967 spring lock nut is a good solution for improving the reliability of threaded connections. Its spring design helps prevent self-loosening, which is especially important under vibration. The zinc coating provides additional corrosion protection and helps extend product service life under suitable operating conditions.

The nut is available in different sizes, allowing it to be selected for standard bolts and screws. When choosing this nut, it is important to check the thread diameter, thread pitch, material, coating, and load requirements to ensure compatibility and reliable connection performance.

Where It Is Used

The DIN 7967 spring lock nut is used in many industries, including mechanical engineering, automotive applications, installation work, and various technical assemblies. It provides secure locking under vibration, helping prevent self-loosening.

When selecting the nut, it is important to check its dimensions, especially the thread diameter, thread pitch, and nut height. The nut is made of zinc-plated steel, providing additional corrosion protection. Before ordering, make sure the selected nut meets the project requirements and is compatible with other connection elements.
