The Simpson Heli-Tie helical wall tie is a Type 304 stainless steel masonry tie engineered to anchor building facades to structural members and to stabilize or repair brick walls. Its helical design allows the tie to be driven quickly and easily into a predrilled pilot hole - or embedded directly into mortar joints during new construction - creating a reliable mechanical connection between a masonry facade and its backup material. As the tie is driven, the fins undercut the surrounding masonry to produce an expansion-free anchorage capable of withstanding both tension and compression loads. The Heli-Tie wall tie performs across a wide range of substrates, including concrete, masonry, wood studs, and steel studs, making it a versatile solution for both new construction and masonry repair and reinforcement applications.

Key Features

• Rotohammer-driven installation in hammer mode - the tie seats faster than competing products, reducing labor time on the jobsite.
• Countersinks up to 1/2 in. below the surface after installation - the recessed tie location can be patched, leaving an inconspicuous repair that preserves the appearance of the building facade.
• Larger core diameter provides higher torsional capacity - minimizes deflection caused by "uncoiling" under load, delivering a more structurally dependable connection.
• Fractionally sized anchor requiring only a 7/32 in. or 1/4 in. drill bit - no metric drill bits needed, so crews can work with standard equipment already on hand.
• Expansion-free helical anchorage - the fins undercut the masonry as the tie is driven, eliminating the stress concentrations associated with traditional expansion anchors.
• Type 304 stainless steel construction - provides long-term corrosion resistance, making these ties suitable for exterior facade and wall tie applications where moisture exposure is a concern.
• Compatible with concrete, masonry, wood stud, and steel stud substrates - a single tie solution covers the full range of common backup materials found in both new construction and retrofit masonry projects.

Why This Product

• Faster installation with standard tools - driven with an SDS-plus shank rotohammer using the proprietary HELITOOL37A setting tool, the Heli-Tie helical wall tie installs more quickly than competing masonry ties, helping keep wall anchoring and facade repair projects on schedule.
• A concealed repair that protects building aesthetics - because the tie countersinks up to 1/2 in. below the masonry surface and the hole can be patched, contractors can reinforce or re-anchor a facade without leaving visible hardware that alters the look of the structure.
• Engineered for load reliability in both tension and compression - the helical fin design undercuts the masonry to create a mechanical, expansion-free lock, so the tie actively resists movement in both directions rather than relying on friction or expansion pressure alone.
• Broad substrate compatibility simplifies procurement - because a single Heli-Tie wall tie works across concrete, masonry, wood stud, and steel stud backup materials, specifiers and contractors can standardize on one product for anchoring building facades and stabilizing brick walls across multiple project types.
