The HTHMQ is a versatile, high-capacity truss hanger designed for various lumber types and multiple-ply trusses. The truss hanger accommodates a greater range of structural designs while accommodating right- or left-hand hips (at 30°- 60° skews), which can be used for terminal hips with or without the center common jack. The HTHMQ can accommodate various widths of lumber.
Key Features
Available in various stirrup widths to accommodate various lumber types and multiple-ply trusses
Installed with Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws that eliminate the inconvenience of bolted installation
Enables 2-3 member connection for a broader range of structural designs
Material
Back plate — 3 gauge; stirrup — 7 gauge
Finish
Simpson Strong-Tie® gray paint
Installation
Use all specified fasteners; see General Notes.
Strong-Drive SDS Heavy-Duty Connector screws supplied with connector.
All multiple members must be fastened together to act as a single unit.
Shall be attached to a minimum double girder truss to allow for required minimum screw penetration. See footnote 5.
Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref ANSI/TPI 1-2014 Section 7.5.3.5).
See Image Gallery for different installation options.
Tabulated allowable loads must be selected based on duration of load as permitted by the applicable building code.
The uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce when other load durations govern.
Specify W1 where applicable and Hip Skew Angle.
Connector must be installed centered on minimum 2x8 vertical web.
A minimum 2-ply carrying member is required for the tabulated loads.
Carrying truss plies must be adequately fastened together as determined by Designer.
Truss chord cross-grain tension may limit allowable loads as determined by the Designer in accordance with ANSI/TPI 1-2014.
Tabulated allowable loads for three-member configurations assume that each hip carries 40% of the total load and the jack carries 20% of the total load. Tabulated allowable loads for single hip-jack configurations assume that 75% of the total load is distributed to the hip and 25% to the jack.
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 1-2014 Section 7.5.3.4 and 8.9.2 are met (pre-drilling required through the plate using a maximum of 5/32" bit).
1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screw may be substituted for the 1/4" x 3" Strong-Drive SDS Heavy-Duty Connector screw provided with the HTHMQ with no load reduction. Back-to-back installations require a 3-ply minimum girder.
