DIN 934 Hex Nuts

Hexagon nuts, specified by the international standard DIN 934, serve as a popular fastener. These nuts feature a six-sided hexagonal shape, providing enhanced grip and resistance to rotation compared to round nuts. They are typically made from steel, but can also be found in materials like stainless steel and brass and come in various sizes and thread pitches to accommodate different bolt diameters and applications. Hexagon nuts DIN 934 find application in a broad range of industries, including construction, automotive, aerospace, and manufacturing. They are essential components for securing bolts and studs in structures, machinery, and assemblies.

Manufactured from various materials
Comprising a variety of sizes
Ensure secure and reliable fastening

Tapered Washers DIN 6921

Tapered washers according to the standard DIN 6921 are a kind of washer designed to be squashed between two surfaces. These washers, typically made from metal, feature a sloped profile which helps to distribute the load across a wider area, effectively minimizing stress on the mating surfaces. This property makes them particularly appropriate for applications where force needs to be applied.

Commonly used in applications involving bolts, tapered washers DIN 6921 can help to avoid loosening and improve the overall strength of a joint.
Furthermore, they can also be used to make up for for slight imperfections between mating surfaces, ensuring a firm connection.
