The H&B Thermal 2-Seal Wing Nut Anchor is an advanced adjustable veneer anchor engineered for metal stud construction. It enhances thermal performance, structural integrity, and moisture resistance by incorporating a dual-diameter stainless steel barrel with pre-installed EPDM washers, ensuring a secure and weather-tight seal on both the insulation face and air/vapor barrier. The reinforced thermal wings, constructed from steel encapsulated in flame-resistant plastic, act as a thermal break to minimize heat transfer through rigid insulation, improving overall energy efficiency. These wings are compatible with 2X-HOOK or Seismic 2X-HOOK pintles, allowing for 360-degree rotation to align pintles/hooks parallel to masonry joints. The anchor also offers up to 1/2” inward adjustability to accommodate wall thickness variations. H&B’s stainless steel barrels provide significantly lower thermal conductivity than standard carbon steel or zinc-coated barrels, making this system a superior choice for energy-efficient construction.
For enhanced seismic adaptability, this anchor system can be used with 9 gauge or 3/16" continuous wire in conjunction with a Seismic 2X-HOOK Pintle. The 2X-HOOK exceeds industry standards, withstanding over 200-lbf in tension and compression, outperforming traditional round wire hooks and pintles by over 100%. Designed for easy and efficient installation, the anchor features a 5/16” hex head, allowing for quick setup with a standard hex socket. The EPDM bonded washer ensures insulation integrity by preventing punctures and reducing penetrations caused by fasteners. Available in multiple barrel lengths (5/8" to 6 1/2"), the H&B 2-Seal Thermal Wing Nut Anchor is an ideal solution for achieving maximum insulation performance, structural stability, and seismic compliance in metal stud construction.
