PAR NUT is a principle that prevents the nut from loosening by pushing the
spring up in the axial direction of the bolt.
The stopper in the housing of the PAR NUT will not release due to the limited
rotational force.
Anti-loosening nut using the tension of the spring, S-NUT
The spring expands when the bolt is connected to support strong connection by reduced friction coefficient of the screw, and the spring contracts when the bolt is loosened to prevent loosening of the nut by increased friction coefficient of the screw. This principle has been applied to the innovative high-performance anti-loosening fastener using the latest technology.
