Description
Essential Load Distribution
Driving a high torque bolt directly into metal, wood, or plastic focuses all the pressure onto a very small area, which can easily crush or deform the substrate.
These Form A washers instantly solve this problem by increasing the bearing surface area. This evenly distributes the clamping force from the nut or bolt head, giving you the practical advantage of a much stronger, more stable joint that won't bite into your materials.
Bright Zinc Plated (BZP) Protection
Untreated mild steel washers will quickly rust simply from the moisture in the air, ruining the look and integrity of your work.
The Bright Zinc Plated (BZP) finish provides a resilient sacrificial coating that shields the underlying steel from oxidation. This guarantees excellent rust resistance for indoor applications, dry environments, and general automotive repairs, while leaving a clean, shiny, professional finish.
Standardized Form A Precision
When you are building mechanical assemblies, mismatched hardware can lead to uneven clamping and compromised safety.
Manufactured to exact DIN-125A specifications, these Form A washers feature a highly standardized thickness and outside diameter. This ensures a perfect, flush fit with standard metric bolts and machine screws, so you always know exactly how the washer will sit within tight clearances.
Convenient 10 Pack Sizing
Sometimes you only need a handful of high-quality washers to finish a specific repair or complete a small project.
Supplied in a highly convenient pack of 10, you can grab exactly what you need without being forced to purchase massive, expensive bulk boxes that will sit unused on your workshop shelf.

Frequently Asked Questions
What is the difference between Form A, Form B, and Form C washers?
What is the difference between Form A, Form B, and Form C washers?
"Form A" denotes a standard, everyday flat washer with a normal thickness and outer diameter. Form B washers are typically thinner, while Form C (or Penny Washers) have a significantly wider outer diameter for spreading loads over an even larger area, such as on thin sheet metal.
Are BZP washers suitable for outdoor use?
Are BZP washers suitable for outdoor use?
BZP (Bright Zinc Plated) offers good basic corrosion resistance, but it is primarily designed for indoor or dry environments. If used permanently outdoors and exposed to heavy rain, they will eventually rust. For exterior or marine projects, you should upgrade to A2 or A4 stainless steel washers.
Can I use these with stainless steel bolts?
Can I use these with stainless steel bolts?
It is generally recommended to match your fastener materials. Using a BZP washer with a stainless steel bolt can lead to galvanic corrosion over time, which will cause the BZP washer to rust prematurely. Always try to pair BZP washers with BZP bolts.
