The Staytite nut

Staytite was founded and owes its name to this simple and effective all-metal lock nut that resists loosening, and outperforms many rival locking nuts on reliability and reusability.

Every Staytite nut is manufactured with a stainless-steel spring insert that engages when installed on a screw thread, flexing upwards. This gives the nut a lower installation torque compared to other types of self-locking nut, particularly those of a deformed thread type.

During operational use, the Staytite nut resists vibration and loosening because the specially designed insert flexes downwards and is ‘pulled’ into closer contact with the screw thread by the upwards anti-clockwise rotation of the nut body.

The Staytite nut is particularly effective when used on a serviceable item. For instance, unlike a nylon insert nut, which should only be used once, the Staytite nut can be used many times. Another advantage of the all-metal design is that it can withstand high temperatures and chemical corrosion in extreme working environments.

The simplicity of the design allows the company to produce the Staytite nut with a range of materials, sizes (metric/ imperial/coarse/fine and extra fine pitch) with variants of the nut to suit almost all types of application. These also include thin, flanged and even weldable types.
