The hexagon nut with serrated flange, conforming to DIN 6923, is a robust fastening solution designed for various industrial applications. Manufactured from hardened carbon steel, these nuts provide excellent strength and durability, making them suitable for high-stress environments. The plain surface treatment ensures compatibility with standard nuts, washers, and inserts, while also allowing for easy integration into existing assemblies. These nuts feature a hexagonal drive, facilitating straightforward installation and removal with standard tools. The right-hand thread direction is typical for most fastening applications, ensuring ease of use. The serrated flange design enhances the locking mechanism, providing a secure grip and reducing the likelihood of loosening due to vibration or dynamic loads. This feature eliminates the need for additional washers, as the flange distributes the load over a larger surface area, thereby minimising surface pressure and accommodating oversized holes. The product adheres to relevant industry standards, including ISO 4161 and NF E25-406, ensuring compliance with stringent quality and safety regulations. While the plain finish offers basic indoor corrosion protection, it is advisable to consider environmental factors when selecting these nuts for outdoor or corrosive settings. Ideal for use in sectors such as automotive, construction, and machinery, these hexagon nuts with serrated flanges are engineered to meet the demands of professional engineers and maintenance personnel, providing reliable performance across a range of applications.
