FAQs

What is a Form G washer?

A Form G washer, also known as a large or penny washer, has a larger outside diameter compared to standard washers. This design is optimized for distributing fastener loads over a wider area.

What does 'zinc galvanised' mean for these washers?

Zinc galvanised means the steel washers are coated with a layer of zinc. This coating provides a sacrificial barrier that protects the steel from rust and corrosion, extending the washer's lifespan, especially in damp or outdoor conditions.

Are these washers suitable for outdoor use?

Yes, the zinc galvanised coating makes them suitable for many outdoor applications due to enhanced corrosion resistance. However, continuous exposure to harsh elements may eventually degrade the coating.

What is the main benefit of using a large flat washer?

The primary benefit is superior load distribution. It prevents fasteners from damaging soft surfaces and reduces the risk of the fastener pulling through the material.

Can I use these washers with any type of screw?

These washers are designed for use with bolts and screws where load distribution is critical. The washer's inner hole size must match the diameter of the screw or bolt you are using.

What standards do these washers comply with?

These washers typically comply with standards such as DIN 9021, ISO 7093, and PN-M 82030, ensuring they meet established quality and dimensional requirements.

How do I store these washers to maintain their condition?

Store them in a dry, indoor environment. Avoid storing them in areas with high humidity or direct exposure to water to preserve the galvanised coating.

Troubleshooting

Washer does not fit bolt/screw

Ensure the washer's inner diameter (e.g., M10) matches the fastener's size.

Corrosion observed on washer surface

This may occur with prolonged exposure to moisture or harsh environments. Clean the surface and consider applying a protective sealant if the application is critical. For extreme conditions, stainless steel alternatives might be more suitable.

Washer is too large for the application

Consider using a smaller diameter washer if the large size is causing interference or is not required for load distribution.

Pros and Cons

Pros

  • Excellent load distribution for secure fastening.
  • Protects surfaces from damage caused by fasteners.
  • Durable zinc galvanised coating offers corrosion resistance.
  • Suitable for heavy-duty and demanding applications.
  • Versatile use across various industries like construction and engineering.

Cons

  • Large size may be unsuitable for small or intricate projects.
  • Can add significant weight to assemblies due to metal construction.
  • Requires appropriate bolt/screw size to maintain hole integrity.
  • Galvanised coating can wear over time with extreme abrasion.

Setup, Compatibility & Care

Setup: These washers are designed to be used with compatible bolts or screws. Slide the washer onto the fastener shaft before inserting it into the material. Ensure the washer's large diameter covers the intended fastening area adequately.

Compatibility: The inner diameter of the washer should match the size of the bolt or screw thread (e.g., an M10 washer is compatible with M10 bolts/screws). These washers conform to international standards like DIN 9021, ISO 7093, and PN-M 82030, ensuring broad compatibility with standard fasteners.

Care: While the zinc galvanised coating provides corrosion resistance, prolonged exposure to harsh chemicals or extreme marine environments may eventually affect the coating. For best results, store in a dry environment. If used outdoors, occasional inspection for any signs of rust or coating wear is recommended. Cleaning can be done with a dry or slightly damp cloth; avoid abrasive cleaners that could damage the galvanised finish.
