Nuts are a fastening device consisting of a hexagonal block with a hole in the centre having a thread that fits on the male threads of an associated bolt or screw. A bolt or screw with a nut is widely used for fastening machine and structural components.These are standard full nuts and washers. Other types are available on the steel nuts and washers page.

Washers are used in conjunction with a screw fastener such as a bolt and nut and that usually serves either to keep the screw from loosening or to distribute the load from the nut or bolt head over a larger area.

It is not necessary to use a washer with nut and bolt. However, they are an excellent addition to protect the surface from damage as they evenly distribute the pressure of the installation and keep the fasteners from corroding. Not using washers can significantly impact the durability of the product.
