META/HETA/HHETA Embedded Truss Anchors

META/HETA/HHETA

The embedded truss anchor series provides an engineered method to properly attach roof trusses to concrete and masonry walls. Information regarding the use of two anchors on single- and multi-ply trusses is included below.

Material

  • HHETA — 14 gauge; HETA — 16 gauge; META — 18 gauge

Finish

  • Galvanized. Some products available in ZMAX® coating. See Corrosion Information.

Installation

  • Use all specified fasteners. See General Notes.
  • The META, HETA and HHETA are embedded 4" into a 6" minimum concrete beam or 8" nominal grouted block wall.
  • For mislocated truss anchors which are greater than 1/8" but less than 1 1/2" from the face of the truss, a shim must be provided. Shim design by Truss Engineer. When gap is greater than 1 1/2", install new anchors.
  • In double embedded anchor installations, do not install fasteners where the straps overlap when wrapped over the truss heel.

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

  1. Allowable loads may not be increased for wind or seismic load.
  2. Minimum f'c = 2,500 psi. Minimum f'm = 1,500 psi.
  3. For simultaneous loads in more than one direction, the connector must be evaluated as described in Note d, under Instructions to the Designer.
  4. It is acceptable to use a reduced number of fasteners provided that there is a reduction in uplift load capacity. Lateral loads do not apply when fewer fasteners are used.
  5. The HHETA allowable F1 load can be increased to 435 lb. if the strap is wrapped over the truss and a minimum of 12 fasteners are installed.
  6. Minimum spacing for multiple anchor installation is two times the embedment depth for full load. See Double Embedded Anchor Installation table below for loads on closer spaced anchors.
  7. Minimum edge distance is 1 1/2" for concrete and 2" masonry.
  8. Lateral loads are limited to 54 mil (16 ga.) CFS members.
  9. See more information on Simpson Strong-Tie fasteners.

Double Embedded Anchor Installation

  1. Allowable loads may not be increased for wind or seismic load.
  2. Minimum f'c = 2,500 psi. Minimum f'm = 1,500 psi.
  3. For simultaneous loads in more than one direction, the connector must be evaluated as described in Note d, under Instructions to the Designer.
  4. Minimum spacing for multiple anchor installation is two times the embedment depth for full load. See Double Embedded Anchor Installation table for loads on closer spaced anchors.
  5. Install with spoons facing outward and straps spaced no more than 1/8" wider than the truss width.
  6. F1 lateral loads listed may cause an additional 1/16" deflection beyond the standard 1/8" limit where the straps are installed not wrapped over the heel as shown.
  7. Lateral loads are limited to 54 mil (16 ga.) CFS members.
  8. See more information on Simpson Strong-Tie fasteners.
