Nyloc Nut is a commonly known name for the nylon inserted lock nut. The lock nuts are used in high vibration systems where the possibilities of loosening the nuts are very high. Suraj Metal Corporationis a leading manufacturer and supplier of the Stainless Steel Nyloc Nuts in different sizes and shapes. The usual nuts can loosen under heavy vibrations.
The lock nuts however take more than just twisting the nuts onto the bolt screws. The Nylock Nut DIN 982 and other specifications cover the different types of lock nuts that have nylon inside the threads. The nylon expands to fit in and to increase the grip. The Nyloc Nut M10 and other sizes are tightened onto the bolt threads and they do not loosen under high vibrations. These nuts are used in different applications such as the Flange Nyloc Nut which is used in piping to fit flanges. As a leading SS Nylock Nut Manufacturer we produce these nuts in different finishes as well. The materials range and the grades of the materials range widely. There are GalvanisedNyloc Nuts and polished lock nuts. The finishes help in reducing the corrosion and wearing off which in turn also increase the grip. We supply the different specifications such as the Hex Nylock Nut DIN 985 and others. Please feel free to contact us for more information and pricing of the different types such as the Grade 8 Nyloc Nuts.
