The Thermal Concrete 2-Seal? Wing Nut is an innovative single screw veneer tie for concrete, CMU, or wood stud construction. The anchor features a dual-diameter barrel with factory-installed EPDM washers to seal both the face of the insulation and the air/vapor barrier, and unique Thermal Wings that are designed to decrease thermal transfer through rigid insulation.
- The projecting Thermal Wings:
- Are made from steel encapsulated in plastic to create a thermal break, the plastic is highly flame resistant
- Accept a 2X-HOOK? or Seismic 2X-HOOK? and spin to easily orient pintles/hooks parallel to masonry joints
- Up to 1/2” of inward adjustability to account for variations in wall thickness
- H&B's Stainless Steel barrels have one-third the thermal conductivity of carbon steel barrels and one-seventh the thermal conductivity of the zinc barrels of our competitors products (refer to chart below)
| Metal Type | Thermal Conductivity (W/cm K) |
| Stainless Steel (Type 304) | 0.15 |
| AISI-SAE 1020 (Plain Carbon Steel) | 0.52 |
| Zinc (Commercial) | 1.1 |

- Made with a 5/16” hex head, install with a standard hex socket
- Adaptable for seismic zones with the simple addition of 9 gauge or 3/16" continuous wire and a 2X-HOOK? Seismic Pintle (SH)
?
The compressed leg 2X-HOOK? has been tested and designed to withstand over 200-lbf, in tension or compression, at maximum allowed offset (ACI 530 6.2.2.5.5.4) of 1-1/4” (disengagement of the pintle from the veneer anchor). These results exceed BIA recommendations and the capabilities of standard “round wire” hooks or pintles by over 100%!
- NOTE: 2X-HOOK? CAN BE INSTALLED WITH LEGS POINTING UP OR DOWN.
- The embedded portion of the 2X-Hook is 3/16”DIA round wire, satisfying the code requirement that the mortar bed thickness (typically 3/8”) must be twice the diameter of the wire.
- 2X-Hook: U.S. Pat. No. 8,613,175 Test results available upon request.
