Types of nuts
Nuts come in a variety of sizes and shapes, each one specifically designed with its own purpose and function. From full nuts and wing nuts to dome nuts, find out more about all of the different types of nuts available at Speedy Fixings below.
Hexagon Full Nuts
Full nuts are the most common type of nut used in a variety of applications. These feature a hexagon shape and are generally stocked as zinc plated, galvanised and stainless steel. Also Nylon and Brass are available.
Nyloc nuts, also known as nyloc insert nuts, come with a nylon band that provides a strong locking connection on the bolt or screw.
Half (lock) Nuts
Also referred to as thin nuts, half lock nuts are a type of standard lock nut that is half the thickness. These are usually used in combination with other nuts to stop them from loosening.
Dome nuts, cap nuts or acorn nuts get their name from their dome-shaped cover, which protects the threaded end of a fastener, acting as a shield against potentially dangerous fasteners or to give an aesthetically pleasing finish.
Security nuts are available in a wide range of styles, many of which require a setting tool that is specific to that particular nut. At Speedy Fixings, we stock a variety of shear nuts which feature the shape of a rounded cone combined with a standard hexagon nut, which will shear off when the required tightness is obtained. Once this happens, it will leave behind the rounded cone which can only be removed by cutting off.
Wing nuts or butterfly nuts have wings on each side that provide a grip in order for them to be easily tightened or loosened by hand.
Channel nuts are designed to be used in Unistrut style channel support systems. These are narrow rectangular nuts with grooves on the edges that grip to the channel struts. They are available as plain nuts or spring channel nuts also known as Zeberdees!
Wedge nuts, Vee nuts or V nuts are used to fix composite flooring systems.
Serrated Flange Nuts
Serrated flange nuts feature a wide flange that works as an integrated washer, which distributes the pressure of the nut. This flange reduces the risk of damage and makes it less likely for the nut to loosen.
Stover Locking Nuts
Stover locking nuts can withstand severe vibration and shock loads, as well as temperatures of up to 230°C. These are commonly used in farm machinery, metalworking industry and automotive industry.
Many of our nuts are stocked in Bright Zinc Plated, Galvanised and stainless steel grade A2 (standard) or A4 (marine grade).
