3/8″ x 8″ Heli-Tie Helical Wall Tie – Stainless Steel Faade Anchoring

Designed for fast, reliable installation, the helical profile allows the Heli-Tie to be driven into a predrilled pilot hole using an SDS-Plus rotohammer and the proprietary HELITOOL37A installation tool. This method creates a strong mechanical bond while minimizing disruption to existing masonry surfaces.

Key Features

• 304 Stainless Steel Construction: Provides excellent corrosion resistance for exterior and long-term use.
• Helical Design: Enables quick installation with strong mechanical interlock.
• Faade-to-Backup Anchoring: Designed to secure masonry veneers to structural members.
• Tool-Driven Installation: Installs with an SDS-Plus rotohammer using the HELITOOL37A.

Common Applications

• Masonry faade repair and stabilization
• Anchoring brick or stone veneers to CMU backup walls
• Building envelope reinforcement
• Restoration and retrofit masonry projects
• Residential and commercial exterior wall systems

Installation Tips

• Drill a pilot hole through the faade and into the backup material to the specified embedment depth plus 1″.
• Use rotation-only mode when drilling into soft masonry or hollow backing materials.
