Plain Washers - Product Grade A GB /T 97.1, flat washers DIN 125 ASME B 18.21.1 EN ISO 7089 equivalent size

Our GB/T 97.1 Product Grade A Plain Washers are engineered for seamless integration into your automotive assembly processes:

• Standardized Dimensions: Manufactured to strict GB/T 97.1 standards, they offer consistent dimensions, ensuring compatibility with standard metric bolts and nuts commonly used in automotive manufacturing.

• Precision Grade (Grade A): Product Grade A signifies tighter tolerances and lower surface roughness compared to Grade C. This precision ensures accurate seating and reliable performance in more demanding or precision-critical automotive assemblies.

• Simple Design: The straightforward circular profile allows for quick and easy placement onto bolts or under nuts, contributing to efficient assembly line operations.

• Smooth Bearing Surface: Provides a consistent, low-friction surface for the rotation of nuts or bolt heads during tightening, aiding in achieving accurate torque and proper preload.

Key Advantages for Your Automotive Applications:

Leveraging GB/T 97.1 Product Grade A Plain Washers in your assemblies provides significant benefits:

• Optimal Load Distribution: Effectively distributes the clamping force of a fastener over a larger bearing surface, reducing localized stress on the joined materials and preventing damage, especially crucial when working with softer or painted surfaces common in automotive interiors and exterrals.

• Surface Protection: Acts as a protective barrier between the rotating fastener and the component surface, preventing scratches, marring, or deformation during tightening and over the lifespan of the vehicle.

• Improved Joint Integrity: By ensuring proper load distribution and preventing surface damage, these washers contribute to maintaining consistent preload and enhancing the overall stability and longevity of bolted connections, which is vital for vehicle reliability and safety.

• Accommodation of Oversized Holes: Can help bridge slightly oversized or irregularly shaped holes, providing a sufficient bearing surface to ensure a secure connection where precise hole alignment might be challenging.

• Cost-Effective Reliability: Offers a simple, standardized, and economical solution for enhancing the reliability of bolted joints in a wide range of automotive applications.

• Compliance with Standards: Adherence to GB/T 97.1 ensures you receive a product meeting defined national quality and dimensional specifications.

Ideal for:

GB/T 97.1 Product Grade A Plain Washers are ideally suited for a wide array of automotive applications, particularly those requiring standard setting and good load distribution:

• General Assembly: Used in countless non-critical fastening points throughout the vehicle, including securing brackets, covers, and non-structural components.

• Body Panel Attachment: Distributing load when fastening interior or exterior body panels and trims to prevent deformation of the panel surface.

• Connections on Softer Materials: Providing a stable bearing surface when fastening materials like plastics, composites, or painted metal surfaces.

• Seating and Interior Fixtures: Ensuring secure and damage-free attachment of seats, consoles, and other interior components.

• Engine Bay Components: Used in various non-critical fastening points within the engine compartment.

• Standard Repairs and Maintenance: A ubiquitous component for replacement in automotive repair and maintenance tasks.

• Applications Requiring Consistent Torque: Contributing to more accurate torque application by providing a consistent bearing surface.
