Thomson currently has two account systems - one for the website and CAD model downloads, and one for e-commerce. We understand that two logins is an inconvenience and are working to consolidate our systems into one login process. Until we’re able to consolidate the two logins, please follow these guidelines:
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.
