Simpson Strong-Tie THM230/38 38mm Mono Truss Hanger 38mm x 96mm Pre-Galv

Purpose-Built Hanger for Mono Trusses with Advanced Nailing Features

The Simpson Strong-Tie THM (Truss Hanger Mono) is a heavy-duty, one-piece joist hanger designed specifically for supporting mono trusses from timber members. Replacing older LUS and HUS models, the THM offers increased efficiency and strength with two flexible installation methods and advanced fixing technology.

Key Features

• Non-Welded Construction: Manufactured from a single piece of pre-galvanised steel, eliminating weld fatigue and increasing structural integrity.

• Two Installation Options:

  • Square twist nails only

  • Square twist nails with Double Shear Nailing, guiding 75mm nails into the joist at a 45° angle for improved load transfer and easier installation.

• Speed Prongs: Assist in holding the hanger in place before final fixing, enabling faster and more precise placement on-site.

• Double Shear Nailing Advantage: A Simpson Strong-Tie innovation, this feature enhances nail engagement and reduces installer effort by allowing straight hammering rather than swinging sideways.

Benefits

• Engineered for mono truss applications where traditional hangers fall short

• Faster installation with integrated speed prongs

• Improved structural performance through angled shear nailing

• Replaces older LUS and HUS models with better versatility and installation ease

• Pre-galvanised finish ensures corrosion resistance in sheltered environments

Applications

Perfect for supporting mono trusses in residential, commercial, and prefabricated timber roof structures. Ideal for sloped roof systems, extensions, and angled roof truss installations where reliability and speed are essential.

Important Notes

• Always use the appropriate square twist nails and follow Simpson Strong-Tie installation instructions for full structural performance.

• Double shear nailing is recommended wherever possible to maximise strength and ease of installation.
