The Heli-Tie™ is a stainless steel helical tie used to anchor building façades 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 façade and its backup material or between multiple wythes 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 is installed using a proprietary setting tool that is used with an SDS-Plus shank rotohammer to drive and countersink the tie. Heli-Tie performs in concrete and masonry as well as wood and steel studs.
FEATURES
- Installs quickly and easily - With the rotohammer in drill and 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" below the surface, allowing the tie location to be patched.
- Corrosion resistant stainless steel.
- Larger core diameter provides higher torsional capacity resulting in less deflection due to “uncoiling” under load.
- Fractionally sized anchor - no metric drill bits required.
- Patented manufacturing process results in a more uniform helix along the entire tie allowing easier driving and better interlock with the substrate.
- “Simpson Heli-Tie” printed on every tie for easy identification and inspection.

Heli-Tie Installation Tool - Model HELITOOL37
Required for correct installation of Heli-Ties. Speeds up installation and automatically countersinks the tie into the façade material up to 1/2". The recessed end of the drive pin frictionally imparts torque onto the tie causing it to thread into the pilot hole faster than competing ties. The cutaway at the tip prevents drill dust from jamming the tie in the tool and allows visual verification of how far the tie has been driven. Features an SDS-Plus shank and is designed for use in rotation and hammer mode. Installation tools sold individually.

Heli-Tie Tension Tester - Model HELITEST37A
Recommended equipment for on-site testing to accurately determine load values in any specific structure. The Heli-Tie tension tester features a key specifically designed to grip the Heli-Tie and provide accurate results. Replacement test keys sold separately (Model HELIKEY37A).

Installation Sequence
- Drill pilot hole through the façade material and to the specified embedment depth + 1" in the backup material using appropriate drill bit(s). Drill should be in rotation only mode when drilling into soft masonry or into hollow backing material.
- Position the Heli-Tie in the installation tool and insert the tie into the pilot hole.
- With the SDS-Plus rotohammer in rotation and hammer mode, drive the tie until the installation tool shoulders up to the exterior surface of the masonry and the drive pin is fully extended. The installation tool will countersink the tie below the surface. Patch the hole in the façade using a color-appropriate material.
