DIN 933 specifies the specifications for high-strength hexagon head bolts. These bolts are widely used in applications where a firm connection is required. They possess a hexagonal drive, which allows for efficient fastening with common tools. DIN 933 bolts are supplied in numerous sizes and materials to accommodate a variety of structural needs.

• Frequent deployments for DIN 933 bolts include automotive assemblies, machinery, and general engineering
• These bolts are renowned for their robustness and dependability under heavy duty conditions
• Compliance with DIN 933 specifications promotes uniformity across various producers

Countersunk Hexagon Head Screws DIN 931

DIN 931 specifies the technical requirements for countersunk hexagon head screws. These fasteners are characterized by their hexagonal socket heads, which are designed to sit flush below the surface of the material when tightened. This characteristic facilitates for a smooth and uniform finish, making them suitable for applications where aesthetics are important. DIN 931 screws are commonly used in various industries, including automotive, aerospace, and electronics.

• Applications of DIN 931 Screws:
• Automotive assembly
• Electrical components mounting
• Aerospace hardware applications
• Furniture

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.

• Produced from diverse materials
• Comprising a variety of sizes
• Provide secure and steadfast fastening

Tapered Washers DIN 6921

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

• Commonly used in applications involving screws, 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 tight connection.
