Premium M1.6-M64 Flat Washers: Essential Load Distribution Solutions

Our M1.6-M64 Flat Washers, frequently referred to as Plain Washers, are the foundational components for any secure fastening system. Engineered to increase the bearing surface area of a bolt or nut, these flat spacers effectively distribute the clamping force, preventing surface deformation and ensuring a stable connection. Manufactured strictly to DIN 125 and DIN 9021 standards, our washers provide the precision and reliability required for both heavy-duty construction and delicate electronic assemblies.

As a leading flat washer factory, we offer a vast inventory of sizes ranging from micro M1.6 to industrial-scale M64, available in high-performance materials like 316 Stainless Steel and Hot Dip Galvanized Steel.

Key Advantages of Our DIN 125 & DIN 9021 Washers

  • Uniform Load Distribution: Prevents bolts and nuts from pulling through the material, especially in softer substrates like wood or plastic.
  • Extensive Standard Range: We provide DIN 125 (Standard OD) for general use and DIN 9021 (Large OD) for applications requiring a wider bearing surface.
  • Burr-Free Precision: Our high-speed stamping process ensures perfectly flat surfaces and clean edges, reducing the risk of scratching the host material.
  • Corrosion Resistance: Choose Stainless Steel SS316 for marine use or Zinc Plated for cost-effective indoor mechanical projects.

Applications Across Heavy Industry & ConstructionOur M1.6-M64 Plain Washers are indispensable in various sectors:

  • Automotive & Aerospace: Reducing vibration-induced loosening in engine and chassis components.
  • Steel Structure: Using Hot Dip Galvanized washers in bridge building and architectural framing.
  • Marine Engineering: SS316 flat washers are essential for preventing galvanic corrosion in saltwater environments.
  • Furniture Assembly: Providing a professional finish and protecting wood surfaces during tightening.

Flat Washer Frequently Asked QuestionsQ: What is the difference between DIN 125 and DIN 9021?
A: DIN 125 is the standard flat washer. DIN 9021 (Large Series) has an outer diameter approximately three times the thread diameter, offering a much larger bearing surface.

Q: Do you provide washers in custom hardness like 200HV?
A: Yes, we provide heat-treated carbon steel washers with hardness ratings of 140HV, 200HV, and 300HV to meet high-strength bolt requirements.
