Discover more about the Imperial Hexagon Nuts range.

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.

Imperial Hex Nut Materials

Components in this range can be manufactured from A2 and A4 Stainless Steel, in either natural or Matte Black finish, or from Mild Steel (Grade 4.6) with a Zinc Plated option available for added corrosion resistance.

Imperial Hexagon Nuts

Accu's Imperial Hex Nuts are available in UNC, UNF and BSW thread types, with manufacturing standards BS 57, BS 1083, BS 1768, ANSI B18.2.2 and ANSI B18.6.3 available.
