Stainless Steel Flat Washers

Stainless steel washers offer a reliable and cost-effective solution when used in combination with a fastener and applied to an application. Stainless steel washers are high quality products that unlock many advantages when compared to flat washers constructed from other materials. Stainless steel washers provide a high level of resistance to corrosion and excellent strength and durability. This also extends to a great temperature resistance, with stainless steel washers able to perform well in both low and high temperatures without losing their mechanical properties. Stainless steel washers have a decent strength-to-weight ratio, meaning they are able to handle heavy loads while being relatively lightweight. As a non-porous metal, stainless steel washers will not harbour bacteria or contaminants, which is an important considering for industries with strict hygiene requirements. Finally, stainless steel washers are fully recyclable and at the end of their application it will generally be possible to reuse or recycle them.

We supply many different styles of flat washers, each designed for slightly different applications. This adds to the versatility of stainless steel washers and means that there is a suitable solution available for every project. The most common types of stainless steel flat washers are known as penny washers and Form A washers. There are also Form B washers, Form C washers and Form D washers. These could also be described using their DIN or BS standards. An Form A washer is also known as a din125a, and Form B and Form C washers use the bs4320 standard. Finally, din9021 are another common variation of stainless steel washers.

We are proud to stock stainless steel washers in a huge range of sizes from M1 all the way up to M56. M10 washers and m12 washers are our two most popular sizes of flat washers. Customers also find the m4 washers and m5 washers useful for a wide range of applications. Looking at the penny washer style specifically, our most commonly purchased products are m6 penny washers and m8 penny washers. In the unlikely event that you need a size of washer that you can't see listed, please do let us know via our contact us page and we'll do our best to source it for you.

The term Form A washers is used to refer to a specific type of stainless steel washer that conforms to a particular standard. This generally will mean that these flat washers have a certain material composition, dimension or tolerance. It helps to ensure consistency and quality across the many different washer products available by loosely placing them into groups of attributes. For example, Form A washers are considered to have a normal thickness and size that makes them suitable for most standard applications. Our Form A washers come in the iso7089 standard which describes a specific set of dimensions that falls within the Form A grouping. There are also Form B, Form C and Form D washers. Form B washers have a thinner thickness when compared to the general purpose Form A. This makes them suitable for applications where space is more limited. Form C washers have a larger outer diameter, in comparison to Form A. This means they provide a larger load-bearing surface area and allows them to offer increased stability and support. Finally, Form D washers offer both a larger outer diameter and an increased thickness when compared to Form A. This makes them a high strength washer that is suitable for heavy duty applications. Together the Form A grouping along with ISO standards are used to explain the specific use cases and specifications of different stainless steel washers, and ensure consistency in their design and manufacturing.

Penny washers are typically a type of stainless steel washer that has a round shape and a large outer diameter in proportion to its inner hole diameter. The name penny washer is said to have originated from the fact that historically, these washers could be purchased for a price of one penny. Penny washers are very commonly used in construction and DIY applications in the UK. Their design is well suited to distributing the load of a threaded fastener, such as a bolt or a screw over a larger surface area. The large outer diameter of the penny washer provides good stability and can help to prevent damage occurring to softer materials like wood or plastic when they are fastened. Penny washers are typically constructed from stainless steel which adds excellent corrosion resistance and high strength to their offering. In summary, penny washers are a useful go-to washer that will perform well in most applications.
