DIN 933 defines the specifications for durable hexagon head bolts. These bolts are frequently utilized in applications where a tight connection is required. They typically feature a hexagonal drive, which ensures efficient fastening with common tools. DIN 933 bolts are offered in diverse sizes and materials to satisfy a spectrum of engineering needs.

• Common applications for DIN 933 bolts include mechanical assemblies, machinery, and general engineering
• These fasteners are celebrated for their durability and reliability under significant stress
• Conformance with DIN 933 specifications promotes compatibility across different manufacturers

Hex Socket Countersunk Head Bolts DIN 931

DIN 931 specifies the technical details for countersunk hexagon head screws. These screws are characterized by their hexagonal driving surfaces, which are designed to sit flush below the surface of the material when installed. This feature allows for a smooth and flush finish, DIN 934 making them appropriate for applications where aesthetics are significant. DIN 931 screws are commonly employed in various industries, including automotive, aerospace, and electronics.

• Uses of DIN 931 Screws:
• Vehicle assembly
• Electronics components mounting

DIN 934 Hex Nuts

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
• Comprising a variety of sizes
• Ensure secure and reliable fastening

Tapered Disc Washers DIN 6921

Tapered washers according to 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 reducing stress on the mating surfaces. This feature makes them particularly well-suited for applications where pressure needs to be applied.

• Commonly used in applications involving fasteners, tapered washers DIN 6921 can help to prevent loosening and improve the overall strength of a joint.
• Additionally, they can also be used to adjust for slight imperfections between mating surfaces, ensuring a secure connection.
