MTHMQ Medium-Duty Multiple-Truss Hanger


On This Page

The MTHMQ and MTHMQ-2 are designed for carrying two or three trusses. The design offers concealed flanges and installs with Strong-Drive® SDS Heavy-Duty Connector screws (included) for easier installation.

Key Features

  • Accommodates right- or left- hand hips (at 45° skews) and terminal hips with or without the center jack
  • Strong-Drive SDS Heavy-Duty Connector screws (included) are easy to install and enable the hangers to achieve higher loads with fewer fasteners
  • Concealed-flange design allows for attachment to vertical web members
  • Min. and max. fastening options for added versatility


  • 12 gauge


  • Galvanized (G90)


  • Use all specified fasteners; see General Notes.
  • Can be installed filling round holes only, or filling round and triangle holes for maximum load. For all installations, fill the fastener holes in the bottom of the hanger seat.
  • For installations at panel points with 2x6 bottom chords, do not fill the triangle holes unless approved by the truss designer.

  1. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. A minimum two-ply carrying member is required for the tabulated loads. With single 2x carrying members, use 1/4" x 1 1/2" Strong-Drive® SDS Heavy-Duty Connector screws in the carrying member and reduce the load to 0.60 of the table value.
  3. For installations on 2x6 carrying members not at a panel point, the four uppermost face fasteners are not installed. For installations on 2x6 carrying members at a panel point, fasteners are installed into the round holes only (minimum vertical member sizes are 2x6 and 2x8 for the MTHMQ and MTHMQ-2, respectively).
  4. Tabulated two-member allowable loads assume that 75% of the total load is distributed to the hip and 25% to the jack. It is permitted to distribute 65% to 85% of the tabulated total load to the hip, and the remaining percentage of total load to the jack. The combined hip and jack load may not exceed the published Total Load.
  5. For terminal hips, divide the total allowable load by 2 to determine the allowable load for each hip.
  6. Tabulated three-member loads assume that each hip carries 40% of the total load and the jack carries 20% of the total load. Other hip-jack load distributions are allowed if the load sum for all three carried members does not exceed the total load and the hip members are equally loaded.
  7. Where noted in the table, the total allowable download for the MTHMQ-2-SDS3 (min.) for a three-member connection at the 115/125/160 load duration is 5,400 lb. (DF/SP) and 3,890 lb. (SPF/HF).
  8. Truss chord cross-grain tension may limit allowable loads in accordance with ANSI/TPI 1-2014. 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.
  9. 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 and 8.9.2 are met (predrilling required through the plate using a 5/32" bit maximum).
