This is the one, the original red Supernut®. The SN Thread Mount has been one of Thomson BSA's strongest sellers for the last 25 years. Offered in a wide range of sizes to fit screws from 3/16” to 1 1/2” diameter. Constructed of a proprietary polymer that offers excellent efficiency and wear life, this nut is for those who need a high performance lead screw solution in a compact envelope. If anti-backlash operation is required, try our SNAB or XC products. Offered in thread mount style with optional mounting flanges available.
