Hexagon Nuts are designed to be used with Machine Screws or Bolts to securely fasten two or more components together. This is achieved through a combination of friction of the threads, a slight stretching of the bolt and the compression (or clamping) of the parts being held together.
Nuts and Bolts are often used alongside a Washer, which helps to distribute the fastener load and can also be used for protection and spacing. For applications where additional space saving is required, Imperial Serrated Flanged Hexagon Nuts, a variant with an integrated washer, can be used.
Hex Nuts are also commonly known as Full Nuts and can be installed using tools such as a spanner, socket wrench or a ratchet.
Imperial Thin Hexagon Nuts are typically used for light to medium duty fastenings, having the advantage of a thinner nut length for better space saving on installation.
For heavier duty applications, Imperial Heavy Hex Nuts are recommended.
