SUNLOCK Flat (CSPCSH-410-TPT4-16)

SUNLOCK is an ideal screw that offers strong "tapping" with "small torque." The cross section of the SUNLOCK screw is non-circular with its three vertices shifting spirally. These two features in shape enable smooth screwing with little torque. The female thread is formed with plastic processing, so there are no shavings from cutting. In addition, there is a loosening effect because the gap between the male screw and the internal screw is eliminated by the spring-back effect after molding. Plastic processing during formation creates strong female threads and high retention.
