Crete-Flex® SS4 Masonry Fastenerscrete-flex-logo

Extraordinary Strength and Fastener Performance

Crete-Flex® SS4 Masonry Fastening System is a family of high performance 410 stainless steel masonry anchors. These anchors deliver corrosion resistance, installation consistency, and outstanding performance when working with concrete and hollow block.

Engineering Technology

Oversized Threads: #14 diameter Crete-Flex® Anchors have a .268″ O.D. and .201″ I.D. These root diameters are much larger than standard concrete anchors and help provide exceptional performance, including higher shear values.
Unique Thread Design: Crete-Flex® are made with resilient 40º threads to help enhance thread engagement and “V” notches for efficient tapping. These 2 features help provide exceptional mechanical strengths.

Superior Corrosion Resistance

Special Heat Treatment: Heat treatment is necessary for added corrosion resistance and tapping into the concrete. Typically 410 stainless steel fasteners are case hardened, but this can adversely impact the fastener’s ductility and corrosion resistance. Due to this Crete-Flex® Anchors get a special heat treatment to help allow the 410 stainless steel to retain more of its natural corrosion resistance and ductility.
Unique Finish: Crete-Flex® Anchors all receive Elco’s unequaled Stalgard® coating. In combination with the special heat treatment, Crete-Flex® Anchors boast superior corrosion resistance. Crete-Flex® Anchors showed no signs of red rust, even after 1,600 hours in a salt spray cabinet (per ASTM B117).

Features:
  • 410 stainless steel
  • Oversized #14 diametercrete-flex-screw
    • Shank (unthreaded section): .214″
    • Major thread diameter (O.D.): .268″
    • Minor thread diameter (I.D.): .201″
  • Heavy-duty, V-notched thread with larger cross-sectional area (25% greater than other commonly-used masonry fasteners)
  • Hex washer, flat, hex flange and TrimFit® flat heads available
  • Gimlet point
  • Special heat treatment
  • Silver Stalgard corrosion-resistant finish provides 1600 hours of salt spray resistance
  • Made in the U.S.A.
  • Installed with a 7/32″ carbide-tipped masonry drill bit
Benefits:
  • Exceptionally high shear values and pull out values
  • Enhanced corrosion resistance
  • Easy and consistent installation

Strength Design Power-Stud® Expansion Anchors by Powers Fasteners®

What are Expansion Anchors?

Expansion Anchors can be used to describe the majority of concrete and masonry anchors. Expansion anchors have an expansion mechanism that is designed to compress against the base material. Each style of expansion anchor can have a different expansion mechanism, which can either be a sleeve, slotted shell, slotted stud, or wedge assembly. The expansion mechanisms are actuated by a tapered cone, tapered plug, nail, bolt, or screw depending on the anchor. The compression of the expansion mechanism against the wall of the drilled hole allows the anchor to transfer the load to the base material. Anchors that are expanded by tightening a bolt or nut are considered to be torque controlled anchors.

Which Stainless Steel Anchor Should I Use for Masonry & Concrete?

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.

300 Series Stainless Steel Fasteners

Two new products have caught my eye recently, both 300 series stainless products with unique features. If your job requires fastening and anchoring in exposed, wet areas, coastal, aggressive environments these products are for you.

Bi-Flex™ Bi-Metal Self-Drilling Fasteners combine 300 series stainless steel corrosion resistance with the convenience of self-drilling.

Aggre-Gator™ 300 Series Stainless Steel Bi-Metal Concrete Anchors feature bi-metal technology: a 300 (18-8) stainless steel head and shank fused to hardened steel tapping threads and gimlet point.
