1 1/2" (3.8 cm) Round Corner Square Leads

The 1-1/2” Round Corner Square Power Shaft Screw Anchor is used in areas where additional helices must be installed and greater torque and tension capacity is required. There are two shaft ratings that MPS offers: Ultimate mechanical strength rating is 55,000 lbs (244,652 N) for 5,500 ft-lbs anchors and 70,000 lbs for 7,000 ft-lbs anchors.

Hot Dip Galvanized per ASTM A123.

Description

A complete Power Shaft assembly consists of a lead helix section, extension(s) and guy termination other attachment.  The helix size (diameter) and number of helices are selected for the required holding strength.  The shaft size and rating is selected based on the necessary holding strength and installation torque requirement.  The guy attachment is chosen based on the number of guys.
