Frequently Asked Questions

To further assist you in choosing the nut(s) most suited to your requirements from the drop down lists above and to avoid the need for you to have to raise several commonly asked questions, please note the following:

  1. The washers referred to above are designed to further distribute the load of a threaded fastener such as a screw, nut or bolt. Here in the U.K, washers that were originally the size the old English penny were commonly known as penny washers, although the name is now still used in relation to washers that are much larger than the size of the old penny such as the washers in question. They are also commonly referred to as repair washers or mudguard washers.
  2. The washers are made from grade A4 Stainless Steel (also known as type A4-316 Stainless Steel). One of the components of Stainless Steel is chromium and this helps the washer to resist staining and corrosion A4 Stainless Steel also contains molybdenum and this provides even more resistance to corrosion especially in marine conditions (i.e. in highly corrosive environments such as sea climates and industrial atmospheres with lots of oxidising acids) - this is why the product title refers to the nuts as being ‘marine grade’.
  3. The washers are sized by the fastener they fit and, therefore, the Fits Bolt Type noted in the dropdown list above is the diameter of the outer thread of the bolt (also known as the major diameter) that the internal diameter hole of this washer will fit.
  4. All photographs of our products are provided for illustration purposes only and you need to select from the drop down lists the specifics of each nut you wish to purchase.
