HTHGQ2-SDS Heavy 2-Ply Girder Truss Hanger
A lower-cost alternative to bolted hangers, the THGQ and THGQH hangers for multi-ply girder trusses use Strong-Drive SDS Heavy-Duty Connector screws to provide high load capacities and easier installation compared to bolts. The Strong-Drive SDS Heavy-Duty Connector screws help transfer the load between the plies of the supporting girder when they penetrate all plies.
THGQ and THGQH 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.
The HTHGQ is a high-load version designed to carry multi-ply trusses or composite lumber up to 5-ply girder trusses. For high load capacities and easier installation compared to bolts, the HTHGQ is designed for use with Strong-Drive SDS Heavy-Duty Connector screws.
THGQ — 7 gauge; THGQH/HTHGQ — 3 gauge
Simpson Strong-Tie Gray Paint
Use all specified fasteners; see General Notes.
Can be installed filling round holes only, or filling round and triangle holes for maximum values.
Strong-Drive SDS Heavy-Duty Connector screws supplied for all round and triangle holes. Installation may not require use of all Strong-Drive SDS Heavy-Duty Connector screws.
All multiple members must be fastened together to act as a single unit.
The thickness of the supporting girder must be equal to or greater than the screw length. For applications where the length of the supplied screws exceeds the thickness of the supporting girder, 3" or 4 1/2" screws may be substituted for the longer length screws with no load reduction, or a shim block may be used as approved by the Designer.
Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref ANSI/TPI 1-2014 Section 220.127.116.11).
See Hanger Options information.
THGQH may be skewed 45° for the models shown.
For hem-fir or spruce-pine-fir members, multiply tabulated allowable loads for the skewed THGQH by 0.86. Connector must be installed centered on girder vertical webs.
