DIN 9021

• DIN 9021 designs large, flat washers for various applications.
• Distinct size distributes load evenly, preventing damage.
• Common in construction, automotive, and manufacturing industries.
• Materials include stainless steel, brass, and plastic.
• Compliance ensures secure, reliable fastening systems.

Uses of DIN 9021

• Load distribution: Evenly disperses pressure in fastening systems.
• Damage prevention: Reduces wear and tear on connected surfaces.
• Vibration dampening: Stabilizes connections in machinery or vehicles.
• Spacer: Adjusts spacing or alignment between components.
• Corrosion resistance: Materials protect against rust and chemical damage.
