SN Thread Mount Supernuts

SN Thread Mount Supernuts

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.
