Timberjack timber screws speed installation, enter wood smoother and hold stronger than the leading timber screw. The special "U" shaped thread locks-in at the finish, reducing pullouts by 200%. Bonding timbers together stronger and reducing expensive call backs.
Timberjack timber screws conform with I.C.C.-E.S. reports that allow for the use of polymer-coated fasteners in contact with treated wood. Also, the protective coating exceeds 1000-hour salt spray tests under ASTM B117 and meets 15 cycles of Kesternich tests. Timberjack screws are recommended for ACQ, CA and CCA treated lumber, as well as cedar and redwood construction.
