Simpson Strong-tie Heli-tie 3/8 In. X 8 In. Helical Wall Tie (50-count)

The Heli-Tie helical wall tie is a stainless-steel tie used to anchor building faades to structural members or to stabilize 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 faade and its backup material. 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 into a predrilled hole using a proprietary setting tool with an SDS-plus shank rotohammer to drive and countersink the tie. Heli-Tie wall ties perform in concrete and masonry as well as wood and steel studs.
