DIN 980 lock nut and Stainless Steel Stover Nuts manufacturer in India

Prevailing Torque Nut has a thread locking system that withdraws the screw reverse turning or backing off; all systems provides a thread interference characteristic that withdraws loosening under vibration. They are also named as stiff nuts, prevailing torque nuts, and lock nuts. Prevailing Torque Lock Nuts is one piece, prevailing torque hex nuts with a flat bottom bearing surface and a conical top and chamfered corners. The locking action is made by twisting the top threads. It resists loosening caused by vibration, shock, and other dynamic forces. Since it is a top locking and only its bottom surface is flat, it is as examined as one way lock nuts due to they are installed one way conical top up. It is used in automotive, agricultural equipment and in the metalworking industries, it also known as automation style lock nuts, all metal lock nuts, all steel lock nuts and top lock nuts.

DIN 980 lock nut feature has unique design that stops it from loosening when exposed to vibrations. There are various types of lock nuts, the most common of which are nylon-insert lock nuts and metal lock nuts. Nylon lock nuts feature a layer of nylon material which covers the interior threading. In comparison, metal lock nuts feature a crowned top that can be grooved to secure the nut in place. Stover Nuts is a hexagon all-metal prevailing torque self-locking nut. The self-locking function of the DIN 980V Nut is produced by deflecting the top threads by creating an interference fit that is still effective and can be reused several times. Stainless Steel Stover nuts are resistant to dynamic loads, shocks and vibration.
