SUNLOCK

The cross section of the SUNLOCK screw is non-circular with its three vertices shifting spirally. These two formation features enable smooth screwing with little torque. The female thread is formed with plastic processing, so there are no shavings when cut. In addition, there is a loosening prevention function thanks to the elimination of the gap between the male and female threads due to the post-molding spring-back effect. Plastic processing during molding creates stronger female threads and high retention.
