HGUQ hangers provide similar capacities as HGUS double-shear hangers, but they use Simpson Strong-Tie® Strong-Drive® SDS screws instead of nails for faster and easier installation. In addition, the Strong-Drive SDS Heavy-Duty Connector screws help transfer the load between the plies of the supporting girder when they penetrate all plies.
Galvanized. HDG available; contact Simpson Strong-Tie®. See Corrosion Information.
Use all specified fasteners; see General Notes.
Nails must be driven at an angle through the joist or truss into the header to achieve the table loads.
Simpson Strong-Tie® Strong Drive® SDS Heavy-Duty Connector screws are supplied with the HGUQ.
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.
Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
Wind (160) is a download rating.
Truss chord cross-grain tension may limit allowable loads in accordance with ANSI/TPI 1-2007. Simpson Strong-Tie® Connector Selector® software includes the evaluation of cross-grain tension in its hanger allowable loads. For additional information, contact Simpson Strong-Tie.
Simpson Strong-Tie Strong-Drive screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2007 Sections 220.127.116.11 and 8.9.2 are met (pre-drilling required through the plate using a maximum of 5/32" bit).
SDS 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 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 SDS screws may be substituted for the longer SDS screws with no load reduction.
For installations to LSL, and use the DF/SP table loads.
