Nyloc Nuts - Type P - BSW

The term “Nyloc” is an abbreviation for nylon insert self-locking nut.

Nyloc nuts feature a nylon collar in the top portion of the nut that locks the nut in place by squeezing the threads of the bolt as the nut is tightened. This friction that is created prevents the nut from loosening.

Nyloc nuts can be re-used but it is not advisable, as their efficiency is reduced with every application, until eventually they become ineffective. The effective operating temperature of Nyloc nuts varies by manufacturer but as a rule of thumb, we would advise extremes of -40C to +120C.

The difference between and Type P and a Type T nyloc nut lies in the physical "depth" of the nut.

Type P nyloc nuts are referred to as full or standard nuts as shown here. This designation is used for all thread and material types.

The thread on this type of nut can often (but not always!) be identified by the colour of the nylon insert, with blue signifying metric and white for imperial threads. For further information please take a look at our guides and tips section.

A Type P nyloc nut is the most common type of nyloc nut and is slightly more thicker than a nyloc Type T nut.

BSW (British Standard Whitworth) is an imperial coarse thread first used in standard production by Joseph Whitworth during the industrial revolution. Whilst it is still used in engineering applications all across the world it is less common in the UK where metric threads have generally taken over.
