DIN6927 Zinc Plated All‑Metal Hex Flange Lock Nut

DIN6927 Zinc Plated All-Metal Hex Flange Lock Nut is a professional prevailing-torque self-locking fastener manufactured in full compliance with DIN 6927 industrial standard. Unlike conventional nylon lock nuts, this all-metal flange nut adopts internal thread cold extrusion deformation structure, completely without nylon insert, rubber ring or any non-metal accessories. It realizes stable mechanical anti-loosening effect through thread elastic deformation, solving the failure problem of traditional lock nuts caused by high temperature aging and vibration fatigue.

The integrated hexagonal flange design of this fastener expands the bearing contact area, disperses assembly pressure, protects the mounting surface from scratch and pressure damage, and improves the overall assembly stability and tightness. As a high-reliability anti-vibration fastener, it is widely recognized and purchased by global industrial equipment manufacturers, vehicle part suppliers and engineering machinery factories.

Material & Surface Treatment Advantages

DIN6927 Zinc Plated All-Metal Hex Flange Lock Nut adopts high-quality carbon steel raw materials with uniform material density and stable mechanical tensile strength, avoiding cracking and thread slipping during high-torque assembly. The electro-galvanized surface treatment forms a dense protective zinc layer on the product surface, effectively resisting daily oxidation, rust and slight corrosion, greatly extending the service life of fasteners in indoor and conventional industrial environments.

For harsh working conditions such as outdoor humidity, chemical corrosion and high salt spray, we support customized stainless steel A2-70 material and anti-corrosion surface processes. All surface treatments of this fastener comply with EU environmental protection standards, meeting global industrial export requirements.

Core Product Features

- All-metal high temperature resistance: DIN6927 Zinc Plated All-Metal Hex Flange Lock Nut has no nylon ring, no rubber and other vulnerable accessories, completely avoid the problem of nylon melting and locking failure under high temperature working conditions, suitable for high-temperature equipment assembly that ordinary nylon lock nuts cannot adapt to.

- Strong anti-vibration performance: Relying on professional thread cold extrusion deformation process, the internal thread forms permanent elastic preload. It can maintain stable locking force for a long time under frequent vibration, impact and dynamic load working conditions.

- Integrated flange protection: One-piece flange structure increases the stress area, reduces assembly pressure, protects the workpiece surface, and improves assembly flatness and firmness.

- Reusable & high cost performance: Compared with disposable anti-loosening fasteners, this all-metal locking nut can be disassembled and reused many times under standard assembly torque, with low comprehensive use cost.

- Standard universal compatibility: Strictly follow DIN standard dimensions, perfectly match DIN6921 flange bolts of the same specification, and support replacement and assembly of old equipment worldwide.

Wide Application Scenarios

DIN6927 Zinc Plated All-Metal Hex Flange Lock Nut is specially designed for high vibration and high-temperature industrial assembly scenarios, and is widely used in mechanical equipment, automobile chassis parts, agricultural machinery, engineering equipment, hydraulic systems, power equipment and general industrial manufacturing fields. It is the preferred anti-loosening fastener for equipment parts that need long-term stable operation and are not easy to maintain.Due to its unique high temperature resistance and fatigue resistance, it effectively makes up for the performance defects of DIN6926 nylon flange lock nuts in high-temperature environments, and is favored by professional industrial purchasers and engineering project suppliers.
