Tormeister 24 relies on high-quality fastening technology to increase operational safety and service life.

Application and assembly

The M8 serrated lock nut is typically used in combination with screws and bolts in metal and mechanical engineering. The serrated edge on the flange ensures the nut engages securely with the bearing surface, increasing resistance to loosening. It provides permanently secure connections, especially in areas with vibration, shock loads, or alternating loads.

Safety and occupational safety: Screw connections in load-bearing or safety-relevant areas must always be tightened to the specified torque. Regularly inspect connections, especially in systems subject to strong vibrations. Improper assembly can lead to material failure and endanger personnel.

Practical example

In an industrial conveyor system, conventional nuts were replaced with M8 DIN 6923 serrated lock nuts. The system operates continuously with high vibrations. The integrated serrations reduced retightening intervals and minimized downtime. The result: increased process reliability, reduced maintenance, and a more robust fastening system.

FAQ

What is a serrated lock nut M8 according to DIN 6923 suitable for?

It is used in vibrating or dynamically loaded structures, e.g. in mechanical engineering, metal construction and industrial plants, to prevent the screw connection from loosening on its own.

Can I use the serrated lock nut on painted or coated surfaces?

Yes, in principle that's possible. However, it's important to note that the serrated locking teeth engage with the surface. Critical coatings should be inspected beforehand to avoid damage or corrosion risks.

Is an additional locking washer required?

In many applications, the integrated locking teeth are sufficient. For particularly safety-critical connections, additional locking elements may be necessary as specified by the designer.
