Hexagon Nuts DIN 934

Hexagon nuts, specified by the international standard DIN 934, constitute a common 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.

• Produced from diverse materials
• Offered in numerous sizes
• Guarantee robust and dependable fastening

DIN 6921 Tapered Washers

Tapered washers according to standard DIN 6921 are a type of washer designed to be squeezed between two surfaces. These washers, typically made from steel, feature a sloped profile which helps to spread the load across a wider area, effectively decreasing stress on the mating surfaces. This characteristic makes them particularly suitable for applications where torque needs to be transmitted.

• Frequently used in applications involving bolts, tapered washers DIN 6921 can help to stop loosening and improve the overall durability of a joint.
• Additionally, they can also be used to make up for for slight inaccuracies between mating surfaces, ensuring a secure connection.
