Nylon nuts, also known as Nyloc nuts, are a type of fastener that have a cylindrical body and a square or hexagonal outer surface. They are made of nylon, which makes them strong and resistant to wear and tear.
A distinctive feature of these nuts is the band of nylon material at the end. This nylon collar increases friction so that the nylon nuts are less likely to loosen. They are particularly useful in applications that require repeated assembly and disassembly, as the nylon filling in the centre ensures minimum damage to the material component
