Simpson HELI371200A Heli-Tie 3/8 in. x 12 in. Helical Wall Tie by Simpson is a corrosion-resistant Type 304 stainless steel wall tie engineered to anchor building façades 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 create a reliable mechanical connection between a masonry façade and its backup material. As it is driven, the fins of the tie undercut the masonry to provide an expansion-free anchorage that withstands both tension and compression loads.

Key Features

• Installs quickly and easily - with the rotohammer in hammer mode, the tie installs faster than competitive products
• Provides an inconspicuous repair that preserves the appearance of the building; after installation, the tie is countersunk up to 1/2 in. below the surface, allowing the tie location to be patched
• Larger core diameter provides higher torsional capacity, resulting in less deflection due to "uncoiling" under load
• Fractionally sized anchor - no metric drill bits required
• Performs in concrete and masonry as well as wood and steel studs
• Required drill bit diameter: 7/32 in. or 1/4 in.
• Corrosion-resistant Type 304 stainless steel construction for long-lasting service life
• Installed using the HELITOOL37A Heli-Tie fastener installation tool with an SDS-plus shank rotohammer
