Helical Wall Tie\u003c\/strong\u003e by Simpson is a 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 deliver a 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.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInstalls quickly and easily  -  with the rotohammer in hammer mode, the tie installs faster than competitive products\u003c\/li\u003e\n\u003cli\u003eProvides 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\u003c\/li\u003e\n\u003cli\u003eLarger core diameter provides higher torsional capacity, resulting in less deflection due to \"uncoiling\" under load\u003c\/li\u003e\n\u003cli\u003eFractionally sized anchor  -  no metric drill bits required\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant Type 304 stainless steel construction for long-lasting durability\u003c\/li\u003e\n\u003cli\u003ePerforms in concrete and masonry as well as wood and steel studs\u003c\/li\u003e\n\u003cli\u003eInstalled using a proprietary setting tool with an SDS-plus shank rotohammer to drive and countersink the tie\u003c\/li\u003e\n\u003cli\u003eRequired drill bit diameter: 7\/32 in. or 1\/4 in.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e HELI372000A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Simpson Strong-Tie\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 3\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 20 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Type 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Type 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired Drill Bit Diameter:\u003c\/strong\u003e 7\/32 in. or 1\/4 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Tool:\u003c\/strong\u003e HELITOOL37A Heli-Tie fastener installation tool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Packs of 50 and Cartons of 200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United Kingdom\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApproved Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAnchoring building façades to structural members\u003c\/li\u003e\n\u003cli\u003eStabilizing brick walls\u003c\/li\u003e\n\u003cli\u003eConnecting masonry façades to backup materials including concrete, masonry, wood studs, and steel studs\u003c\/li\u003e\n\u003cli\u003eNew construction installation via embedding into mortar joints\u003c\/li\u003e\n\u003cli\u003eRetrofit and repair applications where an inconspicuous, patchable connection is required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat drill bit size is required to install the HELI372000A Heli-Tie?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe Heli-Tie HELI372000A requires a predrilled pilot hole using either a 7\/32 in. or 1\/4 in. drill bit prior to installation.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat tool is needed to install the Heli-Tie wall tie?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe Heli-Tie wall tie is installed using the proprietary HELITOOL37A Heli-Tie fastener installation tool paired with an SDS-plus shank rotohammer, which drives and countersinks the tie during installation.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat materials can the Heli-Tie HELI372000A be used with?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe Heli-Tie wall tie performs in concrete and masonry substrates as well as wood and steel stud backup materials, making it suitable for a wide range of façade anchoring and wall stabilization applications.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eHow does the Heli-Tie provide corrosion resistance?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe HELI372000A is manufactured from Type 304 stainless steel, which provides excellent corrosion resistance and ensures long-lasting performance in exterior and moisture-exposed building envelope applications.\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003cp class=\"product-note\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Product dimensions may differ from picture.

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. 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. Heli-Tie wall ties perform in concrete and masonry as well as wood and steel studs.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInstalls quickly and easily  -  with the rotohammer in hammer mode, the tie installs faster than competitive products\u003c\/li\u003e\n\u003cli\u003eProvides 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\u003c\/li\u003e\n\u003cli\u003eLarger core diameter provides higher torsional capacity, resulting in less deflection due to \"uncoiling\" under load\u003c\/li\u003e\n\u003cli\u003eFractionally sized anchor  -  no metric drill bits required\u003c\/li\u003e\n\u003cli\u003eInstalled using a proprietary setting tool with an SDS-plus shank rotohammer to drive and countersink the tie\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant Type 304 Stainless Steel construction for long-lasting service life\u003c\/li\u003e\n\u003cli\u003eCompatible with concrete, masonry, wood, and steel stud backup materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e HELI37900A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Simpson Strong-Tie\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 3\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 9 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Type 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Type 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired Drill Bit Diameter:\u003c\/strong\u003e 7\/32 in. or 1\/4 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Tool:\u003c\/strong\u003e HELITOOL37A Heli-Tie fastener installation tool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Packs of 50 and Cartons of 400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United Kingdom\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApproved Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAnchoring building façades to structural members such as concrete block\u003c\/li\u003e\n\u003cli\u003eStabilizing existing brick walls\u003c\/li\u003e\n\u003cli\u003eRemedial masonry repair and façade tie-back to backup structure\u003c\/li\u003e\n\u003cli\u003eNew construction installation by embedding into mortar joints\u003c\/li\u003e\n\u003cli\u003eUse in concrete and masonry substrates\u003c\/li\u003e\n\u003cli\u003eUse with wood and steel stud backup materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eHow is the Heli-Tie helical wall tie installed?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe Heli-Tie wall tie is installed into a predrilled pilot hole using a proprietary setting tool  -  the HELITOOL37A  -  with an SDS-plus shank rotohammer.
