Simpson Strong-Tie's new tension ties
It's the industry’s first nailed-down holdown to achieve a 6,500-lb. load
Simpson Strong-Tie has added the HTTH6.5 to its lineup of HTT heavy-tension ties, which it describes as high-strength solutions for resisting tension loads in post-pour, wood-to-concrete connections.
The patent-pending, code-tested HTTH6.5 is the industry’s first nailed-down holdown to achieve a 6,500-lb. allowable load.
“Previously, when a specifier needed a holdown in the 5,000- to 8,000-pound allowable load range, their options were the HTT5 heavy-tension tie or the HDU8 holdown; however, there is a large gap between the two in both design load and price, and engineers often had to specify the more expensive HDU even if their design loads were just slightly over the HTT5 capacity,” said Bryan Wert, director of connectors & lateral systems for Simpson Strong-Tie. “The launch of the HTTH6.5 offers our customers a more cost-effective solution, with a load range that bridges the gap between those two holdown options.”
Suitable for residential construction and light-frame wood commercial buildings, the HTTH6.5 single-piece tension tie features a four-fold seat that reduces deflection, a tapered base to optimize strength and an optimal nailing pattern that reduces splitting at the end of the post and maximizes individual fastener capacity. It fastens with nails (in standard sizes for pneumatic nailers) or Strong-Drive SD Connector screws. The allowable load is up to 6,500 lb. with nails and increases to 7,650 lb. when installed with SD screws.
