Simpson Strong-Tie, a leader in engineered structural connectors and building solutions, is adding the HTTH6.5 to its lineup of HTT heavy-tension ties, a high strength solution for resisting tension loads in post-pour, wood-to-concrete connections.
The patent-pending, code tested HTTH6.5 is the company’s first nailed down holdown to achieve a 6,500lb allowable load, making this solution an ideal choice when heavier loads are required.
Suitable for residential construction and light frame wood commercial buildings, the HTTH6.5 tension tie features a four-fold seat that reduces deflection, a tapered base to optimise 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 with Strong-Drive® SD Connector screws with an allowable load up to 6,500lb, or 7,650lb when installed with SD screws.
“Previously, when a specifier needed a holdown in the 5,000lb to 8,000lb 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,” says 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.”
