No-Wrench Screw Anchors can be installed to a greater depth to reach a firmer soil by using an extension rod, available in three lengths below. Maximum installing torque is 2300 ft.-lbs. for 11/4″ diameter rod.
No-Wrench Screw Anchors may be installed by hand or machine. The Thimble eye or Triple eye on the rod has a large opening to admit a turning bar for screwing the anchor down. The eye will also fit into an adapter available from most hole-boring machine manufacturers so the anchor may be power-installed. The No-Wrench Screw Anchor consists of a drop-forged steel Thimble eye or Triple eye rod welded to a steel helix. The entire anchor is hot-dip galvanized for long resistance to rust.
