Chance No-Wrench Screw Anchors may be installed by hand or machine. The Thimbleye® eye or Tripleye® 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 Thimbleye® eye or Tripleye® eye rod welded to a steel helix. The entire anchor is hot-dip galvanized for long resistance to rust.
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.
Catalog numbers 4345, 6346 and PS816 may be ordered with a forged Thimbleye® rod rather than the standard Tripleye® rod. To order a Thimbleye® rod simply add "1" to the suffix of the catalog number. Example: Catalog No. 63461.

Note: If hand installed, holding capacity may be reduced by as much as 10% to 20%. Capacity ratings apply to properly installed anchors only. Failure to install within 5° of alignment with the guy load will significantly lower strength.
