Product Description
The Simpson Heavy Strap Tie HST5HDG is a heavy, load-rated, precut strap engineered by Simpson to support heavy, concentrated loads by creating a strong connection between wood girders and piles. Built from 7-gauge steel and finished with a hot-dip galvanized coating, this heavy strap tie delivers the structural integrity demanded by exterior and treated-wood applications where both load capacity and long-term corrosion resistance are critical. Whether reinforcing pile-supported structures or securing timber framing against wind and seismic forces, this strap tie offers a dependable, code-conscious solution for heavy-duty construction.
Key Features
- Installs with machine bolts - uses a bolt-based fastening method for a secure, high-strength connection suited to heavy structural loads
- Designed to resist wind and seismic forces - engineered for lateral load performance, giving builders confidence in high-stress structural applications
- Made from 7-gauge steel - heavy-gauge construction provides the rigidity and load capacity required for connections between wood girders and piles
- Hot-dip galvanized finish - offers extra corrosion resistance compared to standard coatings, making this strap tie well suited for exterior environments and treated-wood applications where moisture and chemical exposure are concerns
- Heavy, load-rated, precut design - arrives sized and ready to install, reducing field preparation time while ensuring consistent performance across structural connections
Why This Product
- Purpose-built for girder and pile connections - the HST5HDG is specifically designed to handle the heavy, concentrated loads that occur where wood girders meet piles, making it a targeted solution rather than a general-purpose strap
- HDG coating stands up to harsh conditions - the hot-dip galvanized finish is the right choice for outdoor structures and pressure-treated lumber applications, where standard galvanizing may not provide adequate long-term protection
- Wind and seismic resistance built in - load-rated performance against lateral forces means this strap tie contributes directly to a structure's ability to meet wind and seismic design requirements
- Trusted Simpson engineering - Simpson straps and plates are recognized for joining and reinforcing joints with simple, versatile solutions, and the HST5HDG upholds that standard with a heavy-duty, precut format optimized for demanding structural work

Frequently Asked Questions
- What fasteners are required to install the HST5HDG?
- The HST5HDG installs with machine bolts - specifically 12 bolts of 5/8 in. diameter, which should also be hot-dip galvanized to match the corrosion resistance of the strap tie.
- What are the dimensions and material specs of the HST5HDG?
- The HST5HDG measures 5 in. wide by 21-1/4 in. long and is fabricated from 7-gauge steel, providing the heavy-duty strength required for load-bearing connections between wood girders and piles.
- Why is the hot-dip galvanized finish important for this strap tie?
- The hot-dip galvanized (HDG) coating provides extra corrosion resistance compared to standard finishes, making the HST5HDG well suited for exterior environments and applications involving treated wood, where exposure to moisture and chemicals can degrade less protected hardware.
- What types of structural applications is the HST5HDG designed for?
- The HST5HDG is a heavy, load-rated strap tie designed to support heavy, concentrated loads by creating strong connections between wood girders and piles. It is also engineered to resist wind and seismic forces, making it appropriate for structural reinforcement in demanding construction projects.
