Flex Technology, Is the Industry Leader in Critical Fastening

Flex Technology

With the harsh winter winding down, it’s a good time to check out the damage that has been caused by the vast amounts of inclement weather. A huge danger from this type of prolonged inclement weather is delayed embrittlement failures. These failures are caused by the presence of hydrogen which is generated in dissimilar metal applications. Galvanic reactions between dissimilar metals such as aluminum and steel, in the presence of moisture, reduces detrimental hydrogen. This can destroy the integrity of fastener grain boundaries, leading to sudden and potentially catastrophic failures.

To cope with such failures, Elco Construction Products has developed a line of products that utilize Flex Technology. This state of the art technology incorporates high performance and near immunity to these delayed embrittlement failures. These fasteners are made from special alloy materials that receive proprietary heat treatments and tempering processes. The Flex Technology line of products far exceed any standard fastening formats available. They allow designers and system manufacturers to manage their risks and enhance the performance of critical connections. All Flex Technology products also feature Stalgard durable, multi-layer, corrosion-resistant coatings, which are engineered to provide optimal performance in demanding construction applications. These finishes are environmentally friendly and are free of chromates and silicates, that might induce hydrogen embrittlement, preventing structural failures. To be sure you have the best fasteners for critical connections on the market, shop for Flex Technology Fasteners here at TannerBolt.com.

Flex Technology fasteners available here at Tanner include the following products.


Stalgard® High-Performance Protective Coatings

Stalgard® is a durable, multilayer, corrosion-resistant coating, engineered to provide optimal performance in demanding construction applications.

Tanner offers several quality fastening products that are coated with Stalgard® finish.  Fasteners coated with Stalgard finish typically show no red rust or other base metal corrosion on significant surfaces even after 800 hours of 5% neutral salt spray exposure (ASTM B117).

Why are architects and building owners demanding Crete-Flex masonry fasteners?

Architects and building owners want broader guarantees and longer
warranties from contractors and design professionals. I’m seeing this
applied to fasteners more and more.

The industry’s application of higher-grade stainless fasteners is on
the rise because high-grade stainless fasteners, such as the
Crete-Flex® SS4, offer aesthetic benefits, structural integrity,
and long-life performance.

Crete-Flex in particular is becoming increasingly popular because of
its corrosion resistance, enhanced ductility, high pull-out and shear
values, and installation consistency to ensure reliable performance.

Corrosion resistance salt spray tests per ASTM B117 show Crete-Flex
beats a Buildex 410 Stainless Tapcon
by 50% (2400 vs. 1600 hours).
