Stainless Steel Washers
Stainless Steel Washers - Stainless Round Washers/Stainless Flat Washers, Stainless Square Washers, Stainless Spring Washers and other Stainless Steel locking Washers such as Stainless Tooth Lock Washers and Stainless Nord-Lock Washers. Also a wide range of Neoprene Washers as well as other types of Rubber and Plastic Washers including Nylon Washers, Neo Washers for Tek Screws and EPDM Washers.
How Stainless Washers and other Washers work
The washer, protective, can be likened to a buffer or sacrificial piece that fits between the head of a bolt or the nut and the surface of the material being fastened together. This is to protect the finish of the component surface especially when a fastening is being rotated on surfaces like powder coating or painted finish. It also spreads the load of the fastening over a greater area which also protects the surface from damage. This is most apparent when using round washers or square washers on timber. Lock washers or Spring Washers are used to help prevent the fastening undoing under torsional or vibratory loads. Neoprene Washers, Nylon Washers, Neo Washers for Tek Screws and EPDM Washers can be used also. These washers are also useful where it is ideal to seperate dissimilar materials to avoid Galvanic Corrosion such as between a Stainless Bolt and Galvanised Carbon Steel bracket.
How to identify Stainless Steel Washers
Washers come in many various shapes, sizes, grades and types. Normally they are identified by the nominal bore or hole size and the outside diameter, there are also different thicknesses for most of the sizes, this allows for flexibility and choice. Following is a list of the Types, Grades, Sizes and Uses for the different categories of Washers.
Stainless Flat Washers or Stainless Round Washers as they are sometimes called, these would be by far the most commonly used washer by all trades for all types of fastenings. They are available in both metric and imperial sizes. As well as a large number of nominal hole sizes there is also a large variety of outside diameters and thicknesses available to choose from. The imperial 1¼” and 7/8” outside diameter washers are commonly called Penny and Half Penny washers respectively. Sometimes they can be called fender washers.
Stainless Square Washers
Stainless Steel Square Washers are a range of larger sized washers that have a distinctive square outside and a round hole in the middle. They are used mainly in the building and construction industry where timber is held together, the washer is used to spread the tightening loads over a greater area.
Stainless Spring Washers
Stainless Steel Spring Washers - Lock or Split are other common names, these washers are used to lock a nut or bolt head from rotating loose. This is achieved by creating tension under the fastening head.
Stainless Nord-Lock Washers
Nord-lock Washers are another type of locking washer that is used in pairs. They work as each pair of washers have cam faces on one side, so that a joint can not loosen see Stainless Steel Nord-Lock Washers.
