NEW! The THGQ and THGQH hangers for multi-ply girder trusses use SDS screws to provide high load capacities and easier installation compared to bolts. Both models offer minimum and optional maximum fastener quantities to accommodate varying design needs. Allowable loads for various girder web member sizes provide additional installation options. MATERIAL: THGQ 7 gauge, THGQH 3 gauge FINISH: Galvanized INSTALLATION: Use all specified fasteners. See General Notes. Can be installed filling round holes only, or filling round and triangle holes for maximum values. SDS screws supplied for all round and triangle holes. Installation may not require use of all SDS screws. All multiple members must be fastened together to act as a single unit. Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref ANSI/TPI 1-2002 Section 7.4.3.5). CODES: See page 12 for Code Listing Key Chart.

Allowable loads have been increased 33% and 60% for earthquake or wind load with no further increase allowed; reduce where other loads govern. 2. Minimum 2-ply girder required for SDS X3 screws. 3. Connector must be installed centered on girder vertical webs. 4. Strong-Drive screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2002 Section 8.10 are met (pre-drilling required).
