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 T nyloc nuts are referred to as thin 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.

The most common thread type in production today. Usually specified as M then a number x another number. This signifies the thread diameter and the length of the fastener.
For example, M4 x 30 means that the major thread diameter (the external distance across the outside of the thread) is 4mm and the length is 30mm. Length is usually measured from the underside of the fastener head.
A2 stainless steel is often referred to as 304 or 18/8 Stainless. 18/8 actually refers to the amount of chromium and nickel in the alloy - 18% chromium and 8% nickel.
A2 stainless is the most common type of steel used for the manufacture of fasteners and is suitable for general use.
