85 Solid Sawn Connectors THA/THAC Adjustable Truss Hangers This product is preferable to similar connectors because of a) easier installation, b) higher loads, c) lower installed cost, or a combination of these features. The THA series extra long straps allow full code nailing and can be field-formed to give top flange hanger convenience. Designed for 4x2 floor trusses and 4x beams, the THAR/L422 has a standard skew of 45 degrees. Straps can be formed to give top flange hanger convenience. PAN nailing helps eliminate splitting of 4x2 truss bottom chords. MATERIAL: See table. FINISH: Galvanized. Some products available in Z-MAX; see Corrosion-Resistance, page 6-7. INSTALLATION: Use all specified fasteners. See General Notes. Two different installation methods may be used: Maximum nailing-Install all face nails according to the table. Nails used for the joist attachment must be driven at an angle so that they penetrate through the corner of the joist into the header.With single 2x carrying members, use 10dx1 nails into the carrying member, and 10d or 16d commons into the carried member, and use 0.81 of the table value for 18 gauge, and 0.68 of the table value for 16 gauge. Minimum nailing-For the THA29, the minimum nailing schedule requires the use of joist double shear nailing as detailed above, and that the strap be field-formed over the header a minimum of 2 ". A minimum of four top and four face nails must be used. For all models except the THA29, the minimum nailing schedule may be followed where double shear nailing is not possible, provided the strap is field-formed over the top of the header a minimum of 1 for the THA213 and THA413, and 2" for all others, and a minimum of four top and two face nails are used.
