Technical Specifications of ISO 7091
ISO 7091 is an international standard that defines the requirements for flat washers used in various industries. These washers are an integral part of any bolted joint, as they ensure even load distribution and protect surfaces from damage.
Dimensions of ISO 7091 Washer
The dimensions of ISO 7091 washers are standardized and depend on the diameter of the bolt or nut with which they are used. The main parameters that characterize the size of the washer are:
- Inner diameter: Corresponds to the diameter of the bolt or nut.
- Outer diameter: Determines the overall size of the washer.
- Thickness: Depends on the diameter and intended use of the washer.
Strength Class of ISO 7091 Washer
ISO 7091 washers are made of various materials and have different strength classes, corresponding to different loads. The choice of strength class depends on the operating conditions of the joint.
Fastener Group ISO 7091
ISO 7091 washers belong to the group of fasteners. They are always used in conjunction with bolts or screws, providing a secure and strong joint.
Materials for Manufacturing ISO 7091
Most often, ISO 7091 washers are made of steel, which provides high strength and durability. However, depending on the operating conditions, other materials can be used, such as:
- Stainless steel: For use in aggressive environments or where corrosion resistance is important.
- Brass: Provides good corrosion resistance and has a high decorative value.
- Aluminum: Lightweight and corrosion-resistant material.
Application of ISO 7091
ISO 7091 washers are widely used in various industries and construction. They are used for:
- Joining metal structures: In mechanical engineering, metal structures, construction.
- Equipment installation: For fastening various equipment components.
- Automotive industry: For joining automotive parts.
- Furniture industry: For joining furniture components.
- Construction: For fastening various structures.
Advantages of using ISO 7091 washers:
- Even load distribution: Prevents local damage to the material.
- Increased joint strength: Provides a more secure joint.
- Corrosion protection: Some washers have special coatings.
- Improved appearance: Can have various coatings and finishes.
Selection of ISO 7091 washers
When selecting ISO 7091 washers, the following factors should be considered:
- Diameter of the bolt or nut.
- Material of the parts being joined.
- Operating conditions (load, environment).
- Requirements for strength and corrosion resistance.
The correct selection of ISO 7091 washers ensures the durability and reliability of any bolted joint.
