Hexagonal 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.

• Manufactured from various materials
• Comprising a variety of sizes
• Provide secure and steadfast fastening

DIN 6921 Tapered Washers

Tapered washers according to standard DIN 6921 are a variety of washer designed to be squashed between two surfaces. These washers, typically made from steel, feature a angled profile which helps to distribute the load across a wider area, effectively decreasing stress on the mating surfaces. This property makes them particularly suitable for applications where torque needs to be applied.

• Commonly used in applications involving screws, tapered washers DIN 6921 can help to avoid loosening and improve the overall durability of a joint.
• Additionally, they can also be used to adjust for slight inaccuracies between mating surfaces, ensuring a firm connection.
