Square-Shaft "SS" multi-helix screw anchors are designed for heavy-guy loading. They have 2.25" square steel shafts. Extension shafts must be coupled to the helix section for installation to the proper depth. For installation tool options, see catalog Section 4A.
SS screw anchors consist of three galvanized components: the lead section, the extension shaft, which includes an integral coupling, and the guy adapter. Extensions and guy adapters include a high-strength bolt and nut.
Typical working torque is 23,000 ft.-lb. and minimum ultimate tension strength is 200,000 lb. Note: Ultimate strength ratings apply to properly installed anchors only. Failure to install within 5° of alignment with the guy load will significantly lower strength.
