The Clamp-Nut is a three-piece fastener that includes an inner sleeve, outer sleeve and a washer. The fastener boasts a hardened surface in the inner sleeve and washer that prevents galling. In addition, the geometry of the three-piece design allows the fastener to safely bring increased mechanical tensioning to high loads.  Standard Clamp-Nuts have a load range that extends to 1.5 million lb; unit sizes extend from 1 ½ in. to 7 in. are standard. Custom-design Clamp Nuts are available in all sizes. www.hytorc.com
