HTHMQ Heavy Multiple-Truss Hanger
Product Details
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 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 multi-ply 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.

Load Tables
- Tabulated allowable loads must be selected based on duration of load as permitted by the applicable building code.
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- Specify W1 where applicable and Hip Skew Angle.
- Connector must be installed centered on minimum 2x8 vertical web.
- A minimum two-ply carrying member is required for the tabulated loads.
- All multi-ply members must be fastened together to act as a single unit, as determined by the designer.
- 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.
- 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).
- 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws (sold separately) may be substituted for the 1/4" x 3" SDS screw provided with the HTHMQ with no load reduction. Back-to-back installations require a three-ply minimum girder.
