Flat Washer DIN125 Yellow Zinc
Product Information
Yellow Zinc Flat Washers come in different sizes and thicknesses, depending on the intended application. They are primarily made of steel or stainless steel, which are durable, resistant to corrosion, and can withstand high pressure and temperature. Steel washers are zinc plated to improve their resistance to corrosion and rust while giving them a yellow tinge. The yellow zinc coating also makes the washer harder, smoother, and more aesthetically pleasing.
Yellow Zinc Flat Washers are common hardware used in construction, metalworking and industrial applications. They are indispensable components to fasten bolts, screws, or nuts onto a surface by distributing pressure and reducing friction during installation. Yellow Zinc Flat Washers are primarily made of metallic materials such as steel and stainless steel and coated with yellow zinc.
Purpose of Yellow Zinc Flat Washers
The primary purpose of Yellow Zinc Flat Washers is to prevent fasteners from loosening or falling off a surface due to vibration, accidental impacts, or temperature changes. By providing a flat, smooth, and evenly distributed surface, they protect the surface from damage and prevent fasteners from sinking, resulting in a loose or wobbly connection. Furthermore, flat washers distribute the load evenly, reducing wear and tear on the fastener and the surface it is attached to.
Properties of Yellow Zinc Flat Washers
Yellow Zinc Flat Washers have several properties that make them ideal for various applications. First, they have a high tensile strength, which means they can withstand a lot of pressure without breaking or bending. This makes them ideal for applications that require high load-bearing capacity. Second, the yellow zinc coating provides a barrier that protects the underlying steel from rust and corrosion, even in harsh environments. Finally, they are low-cost, readily available, and versatile, which means they can be used in a wide range of applications.
Applications of Yellow Zinc Flat Washers
Yellow Zinc Flat Washers find their use in a broad range of applications, including construction, automotive, plumbing, and industrial settings. They are primarily used in construction applications to fasten bolts and screws to wood or metal surfaces. They are used in automotive applications to fasten bolts, nuts, and screws to various engine parts and other automotive components. In the plumbing industry, they are used to fasten pipes, pumps, and other plumbing accessories. In industrial applications, Flat washers are used to fasten machinery parts, heavy equipment, and other metal assemblies together.
Conclusion
Yellow Zinc Flat Washers are essential hardware that plays a crucial role in fastening bolts, screws, and other types of fasteners onto a surface. They provide a flat, smooth, and even surface that distributes pressure and reduces friction during installation. They are cost-effective, easy to install, and readily available, which means they can be used in various construction, automotive, plumbing, and industrial applications. Their yellow zinc coating provides an added layer of protection against rust and corrosion, making them durable and long-lasting.

Common Fastener Materials
Fasteners are fabricated from a variety of materials. These options include metals and polymers. Stainless steel offers strength and corrosion resistance. While polymer options have less strength than stainless, they are a good choice for resisting chemicals. The most common materials are:
- Stainless steel
- Alloy steel
- Low carbon steel
- Medium carbon steel
- Titanium
- Polymers, such as nylon
Finish Options
The use of heat treatments and application of various finishes, also known as “plating,” affects the look and performance of fasteners. Finishes provide material stability and protect the fasteners from corrosion and rust. Below are some common heat treatment and finish benefits:
- Zinc coating – Most common, low cost, resists corrosion and rust
- Galvanized – Superior corrosion protection, anti-seize, higher upfront investment
- Stainless – Great for humid environments, strong, ideal for electrical or mechanical uses
- Black – Adds color, provides better grip, deflects light
