SB Metric Thread Mount Supernuts

SB Metric Thread Mount Supernuts

Thomson has designed and manufactured the highest quality lead screw assemblies in the industry.  Our classic Supernut is now available with metric mounting threads.  Internally lubricated plastic nuts will operate without additional lubrication and no ball recirculation vibration creates less audible noise as compared to ball screws.  Offered with our metric screw line sizes from 10 mm to 24 mm, the nut is colored black to easily differentiate it from the SN inch versions.
