DIN 935 Hexagon Head Bolts: A Comprehensive Guide

This guide provides a detailed overview of DIN 935 hexagon head bolts, covering their specifications, applications, material properties, and quality standards. We'll explore what makes them a reliable choice in various industries, comparing them to similar fasteners and addressing common questions.

Understanding DIN 935 Hexagon Head Bolts

DIN 935 bolts are a common type of hexagon head bolt standardized by the Deutsches Institut für Normung (DIN), the German Institute for Standardization. These bolts are widely used due to their strength, reliability, and versatility. They are characterized by their hexagonal head, allowing for easy tightening and loosening with a wrench. The standard specifies dimensions, tolerances, and material requirements ensuring consistent quality and interchangeability across different manufacturers.

Key Features and Specifications

Key features of a DIN 935 bolt include its:

• Hexagonal head: Provides a large surface area for wrench engagement, reducing the risk of rounding.
• Full thread: The threads extend the full length of the bolt shank.
• Metric threads: Follow ISO metric thread standards.
• Various materials: Available in a range of materials such as steel (including stainless steel), brass, and other alloys, depending on the application’s requirements.
• Variety of sizes:

Specific dimensions such as length and diameter are detailed within the DIN 935 standard and vary depending on the application. Refer to official DIN documentation or reputable fastener supplier catalogs for precise dimensional data. Always ensure compatibility with the mating nut and application before selection. For detailed specifications, consult the official DIN 935 standard.

Material Properties and Grades

The material chosen for a DIN 935 bolt significantly impacts its strength and corrosion resistance. Common materials include:

• Carbon Steel: Offers good strength and cost-effectiveness. Often further categorized by grades (e.g., 4.6, 8.8, 10.9) indicating tensile strength.
• Stainless Steel: Provides superior corrosion resistance, often used in outdoor or chemically aggressive environments. Grades like A2 and A4 are commonly used.
• Brass: Offers good corrosion resistance and is often used in applications where electrical conductivity is important.

Material Grade Comparison

Note: Tensile and yield strength values can vary slightly depending on the manufacturer and specific material properties. Consult datasheets for exact values.

Applications of DIN 935 Bolts

DIN 935 hexagon head bolts find widespread use across various industries and applications. Their robustness and standardized dimensions make them suitable for a wide range of fastening needs. Some common applications include:

• Machinery and Equipment: Securing components in industrial machinery, manufacturing equipment, and automotive systems.
• Construction and Civil Engineering: Used in structural applications and building construction where strength and reliability are critical.
• General Engineering: Suitable for a wide array of engineering projects requiring robust and dependable fasteners.

Choosing the Right DIN 935 Bolt

Selecting the appropriate DIN 935 bolt involves considering factors such as:

• Material strength required based on the application.
• Desired corrosion resistance based on the environment.
• Thread size and length to match the application.
• Head size and configuration.

Consult with a fastener specialist or refer to the relevant engineering specifications for guidance on selecting the correct bolt for your specific needs. Always prioritize safety and ensure compliance with relevant standards.
