Durable galvanised flat washers for secure fastening and corrosion resistance in various agricultural and industrial applications. Available in multiple sizes.
Galvanised Flat Washers
Agricart offers a comprehensive range of high-quality galvanised flat washers designed to provide superior performance and longevity. These washers are hot-dip galvanised, offering an excellent protective layer against rust and corrosion, making them ideal for outdoor and harsh environments common in agriculture. They help distribute the load of a threaded fastener, preventing damage to the surface and reducing the likelihood of loosening over time. Essential for securing bolts, nuts, and screws in machinery, structures, and equipment.
Select the correct washer size to match your bolt/screw diameter. Place the washer between the fastener head and the material surface. Ensure proper tightening to achieve a secure connection without over-tightening, which can damage the washer or material. Ideal for use with galvanised bolts and nuts for consistent corrosion protection.
When purchasing galvanised flat washers, consider the following:
1. **Size (Inner Diameter, Outer Diameter, Thickness):** Match the inner diameter to your bolt/screw size. The outer diameter and thickness affect load distribution and strength.
2. **Quantity:** Determine the number of washers required for your project to avoid shortages.
3. **Application:** Consider the environment (e.g., outdoor, high moisture) to ensure galvanisation is the appropriate protective coating.
4. **Supplier Reputation:** Choose a reputable supplier like Agricart for quality assurance and reliable products.

Ensure proper classification under HS Code 7318.22.00 for washers. Declare accurate material composition and galvanisation process for customs clearance.
All imported galvanised flat washers must meet international quality standards. Verify galvanisation thickness and adhesion. Required documentation includes commercial invoice, packing list, bill of lading/airway bill, and certificate of origin.
For export, ensure compliance with the importing country's regulations regarding fasteners and galvanised products. Provide all necessary certifications and technical specifications.

- What is a galvanised flat washer?
- A galvanised flat washer is a circular disc with a hole in the center, made from steel and coated with a layer of zinc (galvanisation) to protect against rust and corrosion. It's used to distribute the load of a threaded fastener, prevent surface damage, and reduce loosening.
- Why should I choose galvanised washers over plain steel washers?
- Galvanised washers offer significantly enhanced corrosion resistance compared to plain steel, making them ideal for outdoor, humid, or otherwise harsh environments where rust is a concern. They provide a longer lifespan and better performance in such conditions.
- What sizes of galvanised flat washers are available?
- Agricart offers a wide range of sizes for galvanised flat washers, typically measured by their inner diameter (to match bolt size), outer diameter, and thickness. Please refer to our product listings for specific available dimensions.
- Can galvanised washers be used with stainless steel bolts?
- While possible, caution is advised. Using galvanised washers with stainless steel fasteners can lead to galvanic corrosion in certain environments, especially with moisture or electrolytes present. It's generally recommended to use fasteners of similar material or consult an expert for specific applications.
- How does galvanisation protect the washer?
- Galvanisation protects the washer in two main ways: by providing a barrier coating that physically separates the steel from the corrosive environment, and through cathodic protection (sacrificial protection), where the zinc coating corrodes preferentially to the steel, protecting the underlying metal even if the coating is scratched.
