Hexagon Nuts DIN 934

Hexagon nuts, specified by the international standard DIN 934, are a widely used 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.

• Forged from different materials
• Offered in numerous sizes
• Provide secure and steadfast fastening

DIN 6921 Tapered Washers

Tapered website washers according to DIN 6921 are a kind of washer designed to be compressed between two surfaces. These washers, typically made from stainless steel, feature a tapered profile which helps to distribute the load across a wider area, effectively reducing stress on the mating surfaces. This property makes them particularly appropriate 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 strength of a joint.
• Moreover, they can also be used to compensate for slight inaccuracies between mating surfaces, ensuring a secure connection.
