THGQH Heavy Truss Hanger for Girders, Quick-Install
On This Page
Product Details
The THGQH is a heavy hanger designed for a girder truss or a structural composite lumber beam attached to a girder truss. A lower-cost alternative to bolted hangers, the THGQH uses Strong-Drive® SDS Heavy-Duty Connector screws to provide high load capacities and easier installation. The THGQH offers minimum and maximum fastener quantities to accommodate varying design needs.
Key Features
- Strong-Drive SDS Heavy-Duty Connector screws are included to help transfer the load between the plies of the supporting girder when they penetrate all plies
- Increased allowable loads available when wider vertical web is used
- Various models may be skewed 45°
Material
- 3 ga.
Finish
- Simpson Strong-Tie gray paint
Installation
- Use all specified fasteners; see General Notes.
- Fill all round holes; additionally, fill triangle holes to obtain maximum values.
- Strong-Drive SDS Heavy-Duty Connector screws are supplied for all round and triangle holes.
- All multiple carried and carrying members must be fastened together to act as a single unit.
- The screw length should be equal to the assembly thickness of the supporting girder. For applications where the length of the supplied SDS screws does not match the thickness, appropriate-length SDS screws should be used instead.
- Girders must have adequate lateral bracing to prevent excessive displacement due to secondary torsional stresses (refer to ANSI/TPI 1-2014 Section 7.5.3.5).
Options
- 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.

Load Tables
Allowable Loads for Multi-Ply Truss Girder
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- Connector must be installed centered on girder vertical webs.
- Strong-Drive® SDS Heavy-Duty Connector screws may be installed through metal truss plates as approved by the truss designer, provided the requirements of ANSI/TPI 1-2014, Sections 7.5.3.4 and 8.9.2 are met (predrilling required through the plate using a 5/32" bit maximum).
- Strong-Drive® SDS Heavy-Duty Connector screws that penetrate all plies of the supporting girder (screws must penetrate a minimum of 1" into the last truss ply) may also be used to transfer the load through all the plies of the supporting girder. When SDS Heavy-Duty Connector screws do not penetrate all plies of the supporting girder truss, supplemental SDS screws at the hanger locations may be required to transfer the load to the truss plies not penetrated by the face fasteners, as determined by the designer.
- The supporting girder truss must have adequate thickness to accommodate the screw length, so that the screw does not protrude out the back of the girder. 3"- or 4 1/2"-long Strong-Drive® SDS Heavy-Duty Connector screws may be substituted for longer SDS screws with no load reduction.
- For installations to LSL, use 1/4" x 3" Strong-Drive® SDS Heavy-Duty Connector screws and use the DF/SP table loads.
- Wind (160) is a download rating.
Allowable Loads for Structural Composite Lumber (SCL)
- 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
