Our custom nuts meet many widely varying needs in materials such as steel, stainless steel, copper, brass, aluminium, plastic or exotics like titanium. There are many different styles on the market today. Amongst the commonest are the Full Nut, the Lock Nut (sometimes referred to as a Half-Nut or Thin Nut) and the Nylon Insert Self-Locking Nut.
Special shapes include curved combi-washers/collars to fit tubing etc., or castellated designs of varying pitch to allow for indexed adjustment. Options are almost endless, and the final choice is heavily dependent upon the service expectations required.
Essentially conceived as any piece of metal (or plastic) with a thread in it intended to be fixed to a component, special nuts can have C wrench slots, pin wrench holes, may be double-ended or welded (projection weld nut) to a foot plate or bracket. All metal self-locking nuts are available where higher temperatures are likely to be experienced. These include Aerotight, Philidas, Stover, Binx, Cleveloc and many others, all providing anti-vibration loosening characteristics.
Security (anti-vandal) nuts available include Kinmar, both permanent and removable, Tufnuts, Scroll Nuts and the ever-popular Shear Nut. Flange Nuts, both plain and serrated flange, fill another gap where load spreading is required without the need of a washer, while the serrated flange version also provides a degree of resistance to loosening under vibration. The Combi-Nut design is another configuration that provides load spreading where a washer is trapped into the nut but is free to rotate. Versions fitted with an external toothed shakeproof washer can also offer an element of resistance to vibration loosening.
