Simpson HELI371600A Heli-Tie 3/8 in. x 16 in. Helical Wall Tie by Simpson is a Type 304 stainless steel helical 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. The Heli-Tie wall tie performs in concrete and masonry as well as wood and steel studs.

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
• Installed using a proprietary setting tool with an SDS-plus shank rotohammer to drive and countersink the tie
• Corrosion-resistant Type 304 stainless steel construction for long-lasting service life
• Performs in concrete and masonry as well as wood and steel studs

Frequently Asked Questions

How is the Heli-Tie helical wall tie installed?

The Heli-Tie wall tie is installed into a predrilled pilot hole using a proprietary setting tool with an SDS-plus shank rotohammer. With the rotohammer in hammer mode, the tool drives and countersinks the tie quickly and easily. The required installation tool is the HELITOOL37A Heli-Tie fastener installation tool.

What drill bit size is required to install the HELI371600A?

Installation requires a predrilled pilot hole using either a 7/32 in. or 1/4 in. drill bit. Because the anchor is fractionally sized, no metric drill bits are needed.

How far below the surface is the tie countersunk after installation?

After installation, the tie is countersunk up to 1/2 in. below the surface. This allows the tie location to be patched, providing an inconspicuous repair that preserves the appearance of the building.

What substrates and backup materials is the Heli-Tie compatible with?

The Heli-Tie wall tie performs in concrete and masonry as well as wood and steel studs, making it suitable for a wide range of façade anchoring and wall stabilization applications in both new construction and retrofit scenarios.
