Simpson Strong-Tie Introduces Large-Diameter Stainless-Steel Screw Anchors

Simpson Strong-Tie, the industry leader in engineered structural connectors, fasteners, anchors and building solutions, is the first manufacturer to launch large-diameter stainless-steel screw anchors for concrete and masonry. Designed for severely corrosive interior or exterior environments, the new stainless-steel Titen HD heavy-duty screw anchors (THDSS) deliver an advanced standard of performance for bridge, marine and water treatment plant construction and retrofit applications.

The nation’s aging wastewater treatment plant infrastructure is facing a critical turning point, with the American Society of Civil Engineers projecting $206 billion in increased costs to households and businesses if the upgrade and replacement of old treatment plants are not completed by the year 2020. In addition, according to the American Road and Transportation Builders Association’s 2018 Deficient Bridge Report, 54,259 US bridges are structurally deficient. In fact, almost 9% of all bridges in the country have at least one key structural element in poor enough condition to need repair, the report finds.

Available since April 2017 in 3/8″ and 1/2″ diameters, THDSS is now offered in larger 5/8″ and 3/4″ diameters suitable for heavier civil construction where corrosive elements pose a hazard to standard carbon-steel screw anchors.

“There is definitely a need in the market for larger-diameter screw anchors,” says Simpson Strong-Tie senior product manager Mike Steiber. “Other wedge anchor or adhesive options often have drawbacks with spacing or difficult installation, so for applications that need stainless-steel anchors, this is a first-of-its-kind solution for the market.”

Key features and benefits of the THDSS screw anchor: Ideal for exterior applications and corrosive environments Made from Type 316 stainless steel Installs with an impact wrench or a hand tool Now available in 3/8″, 1/2″, 5/8″ and 3/4″ diameters All stainless-steel Titen HD anchors are code listed in IAPMO UES ER-493 (concrete) and ICC-ES ESR-1056 (masonry) for a wide variety of applications and could make a significant impact by improving the structural integrity of bridges via repair and retrofit.

“Wastewater facilities are definitely one of the key markets where these larger-diameter, corrosion-resistant anchors are badly needed,” Steiber says. “The retrofit opportunity is also there for bridges, because right now we’re not repairing these bridges fast enough to make the problem go away.”
