DIN 7967 Spring Steel Self-Locking Lock Nut
DIN 7967 is a hexagon self-locking spring steel lock nut, zinc-plated or in stainless steel A2/A4. FLOK supplies it in bulk batches, sizes M4–M52.
DIN 7967 is a special-purpose hexagon lock nut. The fastener has a round installation hole and notches at the flange corners. The special shape prevents the connection from spontaneously unscrewing and keeps the clamped parts from loosening.
The self-locking lock nut does not require additional locking elements. Nuts of this type can be used in assemblies subject to constant vibration and dynamic loads, ensuring maximum reliability of the connection.
Materials and parameters
Self-locking lock nuts are made of spring steel, which provides high resistance to external effects. To extend service life, the material is coated with a layer of zinc — zinc-plated nuts can withstand corrosion for significantly longer. They can also be made of stainless steel: acid-resistant steel A2 and A4 is used for production, making the material resistant to corrosive environments.
The product is manufactured according to the following specifications:
- The thread diameter of the nut ranges from M4 to M52.
- The overall height of the product varies from 2.5 to 16 mm.
- The width across flats of the nut can range from 7 to 80 mm.
- The diameter of the nut’s circumscribed circle ranges from 8.1 to 92.4 mm.
Nuts of this type have compact dimensions, so they can be used for installation in confined conditions.
Applications
This fastener product is used in various mechanical engineering industries: shipbuilding, automotive manufacturing, machine tool and special equipment assembly, and others. If an assembly is subject to vibration or dynamic loads, nuts of this type guarantee it higher reliability and prevent spontaneous loosening of the connection. A wide range of sizes and ease of installation provide the product with broad application possibilities.
FLOK supplies this type of fastener on wholesale terms, in batches of various volumes. Supply of equivalents is possible: FLOK consultants will provide the necessary information for selection.
