Fasteners for the farming sector: silos and agricultural machinery

The agricultural sector has a special role to play in the national economy, environmental protection and technology innovation. Agricultural machinery and metal silos play a fundamental role in the sector: agricultural machines are a vital operational tool and silos are essential for storing the harvest.

At CHAVESBAO, we offer a range of standardised fasteners for use in the maintenance of farming machinery and construction of silos

Fasteners for agricultural machinery and silos

Using standardised fasteners is the best way to guarantee a safe and secure assembly when maintaining agricultural machinery or building grain silos. In our catalogue, we offer a range of products designed for these types of applications.

  • Silo bolt (similar to DIN 6921): this type of bolt has a hexagonal flanged head with a serrated washer surface to provide greater load-bearing support and increased grip. This type of serrated washer is used in applications where safety and stability are critical, such as on heavy machinery or equipment that is subject to high levels of vibration. Silo bolts have a recess that allows the top of the head to remain flush with the surface of the part that it is attached to. This provides a smoother, more aesthetically pleasing finish.
  • Hexagon nuts: hexagon nuts are manufactured according to DIN and ISO international standards, thereby ensuring compatibility and high-performance in projects all over the world. In addition, their robust design makes them suitable for applications that involve high loads or vibrations as the contact between the flat faces of the nut and the tool provides a secure grip.
  • Self-locking nuts: this type of nut is designed not to come loose when subjected to movement or vibrations. This is done by way of a nylon or metal collar which prevents the nut from rotating freely once tightened. In our catalogue, we offer a wide range of DIN nuts for use in the manufacture of agricultural machinery and silos.
  • Flat washers: flat washers are the perfect component to help uniformly distribute the load on the bolt head. They also protect the surface area of the material by preventing direct contact between the nut and bolt head.

En CHAVESBAO disponemos de una amplia selección de tornillería estandarizada para la fabricación de componentes de aerogeneradores o cualquier otro elemento del sector eólico.

Tornillería estandarizada para aerogeneradores y turbinas eólicas

El uso de tornillos estandarizados garantiza la calidad y seguridad de los productos empleados en la fabricación de los componentes dentro del sector eólico. En nuestro catálogo encontrarás una gama de tornillería que se ajusta a las diferentes Normas DIN que hacen referencia a la composición y estructura de cada uno de los productos:

Tornillos hexagonales

Los tornillos hexagonales aptos para la fabricación de aerogeneradores están fabricados según las Normas DIN 931 y DIN 933 que aplican a su estructura. En el primer caso se componen de cabeza hexagonal y cuerpo cilíndrico con media rosca. Además, los tornillos DIN 931 están disponibles en calidad 8.8 y 10.9. Los tornillos hexagonales DIN 933 incluyen también cabeza hexagonal, pero, a diferencia de los primeros, en estos el cuerpo está totalmente roscado.

Tuercas hexagonales

Las tuercas hexagonales para la fabricación de aerogeneradores y turbinas eólicas se ajustan a la Norma DIN 934 que hace referencia a la composición y estructura de las mismas. Este tipo de tuercas son las más comunes en el mercado y en nuestro catálogo podrás encontrar una amplia selección de productos en calidad 8 y calidad 10 -con diferentes grados de resistencia- que se adaptan según el tipo de componente a fabricar.

Arandelas planas

Las arandelas planas se ajustan a las Normas DIN 125 y DIN 9021. Las arandelas planas DIN 125 se utilizan comúnmente en una amplia variedad de aplicaciones. Sin embargo, las arandelas DIN 9021 son más anchas que las anteriores proporcionando una mayor superficie para la distribución de la carga.
