Tanner offers three different levels of stainless steel anchors for use in concrete and masonry that is subject to corrosive environments.

UltraCon® SS4 is a threaded masonry anchor that offers the same proven performance as UltraCon masonry fasteners with the enhanced feature of 410 stainless steel and Stalgard® protective coating.

In fact, the UltraCon SS4 outperformed Stainless Steel Tapcon® screws in a 1500 hour salt spray test and has higher pull out values. UltraCon SS4 is available in 1/4” diameter in 5/16” diameter Hex Washer Head and #3 Phillips TrimFit Flat Head, from 1-1/4” up to 4” in length. Very easy to use- just drill and drive!

For more demanding applications, such as products utilized for hurricane reinforcement, use Crete-Flex® fasteners which receive a special hardening process during manufacture that maximizes corrosion resistance and ductility. In addition, Crete-Flex fasteners receive the unique Stalgard® coating process for further protection. After 2,400 hours in a salt spray cabinet (per ASTM B117), Crete-Flex fasteners show no signs of red rust.

Easily installed with a commercial-grade hammer drill or rotary hammer and a specially sized Crete-Flex carbide-tipped drill bit.

If your job includes working in an exposed area, such as coastal or wetlands, use Aggre-Gator® Bi-Metal Threaded Anchors. Perfect for installation of aluminum enclosures, hurricane shutters, windows, awnings, thresholds, curtain wall, window, and stone façade support anchors.

Aggre-Gator features a 300 series stainless head and shank with fused and hardened steel tapping threads and a gimlet point, hence “bi-metal” technology. 300 series stainless alloy gives unmatched corrosion protection while the steel tapping threads hold tight in the block and poured concrete. To top it off, coated with silver-colored Stalgard® GB, a Galvanic Barrier to protect aluminum components from accelerated corrosion when in contact with 300 series stainless steel.
