Fastener DIN 934 Stainless Steel M2-M12 Hexagon Hex nut

Hexagon Hex Nut, commonly referred to simply as a Hex Nut, is a type of fastener with a six-sided (hexagonal) shape, designed to be used in conjunction with bolts or threaded rods to secure materials together. Here’s a detailed breakdown of its features and uses:

1. Shape:

• Hexagonal (Six-Sided): The nut has six flat sides, which allows it to be easily tightened or loosened using a wrench, socket, or spanner. The hexagonal shape provides a good balance between ease of use and the ability to apply high torque.

2. Material:

• Hex nuts can be made from various materials, including:

• Carbon Steel: Common for general-purpose applications due to its strength and durability.

• Stainless Steel: Offers excellent corrosion resistance, making it suitable for outdoor or corrosive environments.

• Brass: Used in applications requiring non-magnetic or corrosion-resistant properties.

• Nylon: Often used in applications where electrical insulation or vibration resistance is needed.

3. Thread Type:

• Hex nuts have internal threads that match the external threads of the bolt or threaded rod they are used with. The thread pitch and diameter must correspond to the bolt for a proper fit.

4. Types of Hex Nuts:

• Standard Hex Nut: The most common type, used in a wide range of applications.

• Heavy Hex Nut: Thicker and stronger than standard hex nuts, used in high-stress applications.

• Nylon Insert Lock Nut (Nyloc Nut): Features a nylon insert that provides resistance to loosening due to vibration.

• Jam Nut: Thinner than standard hex nuts, used to lock another nut in place.

• Flange Nut: Has a built-in washer-like flange to distribute the load and provide a locking feature.

  
  

5. Surface Finish:

• Hex nuts can have various surface finishes, including:

• Plain: No additional coating, suitable for general use.

• Zinc-Plated: Provides corrosion resistance.

• Hot-Dip Galvanized: Offers enhanced corrosion protection for outdoor or harsh environments.

• Black Oxide: Provides a protective finish and a sleek appearance.

6. Applications:

• Hex nuts are used in a wide range of applications across various industries, including:

• Construction: For structural fastening.

• Automotive: In vehicle assembly and maintenance.

• Machinery: For securing components in industrial equipment.

• Household: In furniture assembly and general repairs.

7. Standards:

• Hex nuts are manufactured to meet specific industry standards, such as:

• ISO (International Organization for Standardization)

• DIN (Deutsches Institut für Normung)

• ANSI (American National Standards Institute)

• BS (British Standards)
