The Heli-Tie is a stainless-steel helical tie used to anchor building facades to structural members or to stabilize Multiple-Wythe brick walls. The helical design allows the tie to be driven quickly and easily into a predrilled pilot hole (or embedded into mortar joints in new construction) to provide a mechanical connection between a masonry facade and its backup material or between multiple Wythe's of brick. As it is driven, the fins of the tie undercut the masonry to provide an expansion-free anchorage that will withstand tension and compression loads. The Heli-Tie wall tie is installed using a proprietary setting tool that is used with an SDS-Plus shank rotohammer to drive and countersink the tie. Heli-Tie wall ties performs in concrete and masonry as well as wood and steel studs.
