As a supplier of construction products and equipment, Power Bolt and Tool considers the needs of every level of the construction industry to be a priority. Planning engineers have to know that the products needed for the integrity and durability of the project being planned will be met. The construction companies doing the job have to be able to rely on products that are going to meet the required specs but still be cost effective. The tradesmen doing the job must know that they are working with ease of use products in order to maintain their productivity. Power and Bolt knows the importance of these requirements and ensures that these are all met through each product that is provided. The Aggre-Gator 300 Series-Stainless Steel Concrete Anchors come into this category, and more than meet the criteria that have been set for them.


When to choose the Aggre-Gator 300 series

These stainless steel concrete anchors should be the first choice when the job demands the need for top quality Elco fasteners that have the ability to resist corrosion and are required for concrete anchoring that leaves no room for inferior performance. When the project is going to be completed in environments that create wetness and dampness, the level for potential corrosion is dramatically heightened. It won’t be an area of concern for those building the structure when they rely on the Aggre-Gator concrete anchors. For jobs such as those that are comprised of aluminum enclosures for hurricane protection such as shutters, these should be the fastener of choice, along with them being applicable for a large selection of other types of applications.

What makes the Aggre-Gator 300 Series-Stainless Steel Concrete Anchors the fastening system of choice?

It begins with the quality of materials that these Elco fasteners for concrete are comprised of.

Aggregator product
They are made with the best of quality 300 series stainless steel, and then additional anti-corrosion protection is in place with the Stalgard® galvanic barrier coating. What this means is that the alloy components of the stainless steel prevent Hydrogen assisted stress corrosion cracking which means no concerns are needed for the prevention of embrittlement.

The design supports the integrity of the materials that make up this construction fastener with the head and shank being comprised of the 300 series stainless steel, and the tapping threads, as well as the gimlet points, being fused hardened steel. This is what the impressive Bi-metal technology is comprised of.



The additional benefits of this Top performing Elco fastener

While stainless steel concrete anchors have to meet the high standards it is designed for, it also has to possess qualities that make it easy to use. Ease of use means increased speed but without compromising the integrity of the structure it is being applied to. The quality components and the fused self-tapping point allow for precision work with little effort.


The longevity and appearance counts

Aside from the all-important durability and strength that the Aggre-Gator 300 Series-Stainless Steel Concrete Anchors provide, they won’t fail in their performance for longevity. Structures that have been built using these Elco fasteners for concrete can be counted on to maintain the same integrity they have the day they are installed up to many years later.

Aggregator 300 series bi-metal
The 300 Series Stainless Bi-Metal Masonry Fasteners from Elco is called Aggre-Gator. The 300 series stainless steel is well recognized as being highly resistant to corrosion. Also, it continues to maintain its strength at high temperatures. Above all, 300 series stainless steel is very easy to maintain. Its metal composition includes chromium, nickel and molybdenum.

To make things significantly better than before, Elco has decided to take this series a step further by making Aggre-Gator the number one corrosion resistant 300 series stainless steel in a threaded concrete anchor.


300 Series Stainless Aggre-Gator Flex Technology®

Aggre-Gator is made of 300 series stainless steel (18-8) alloy, which provides unmatched corrosion resistance in even the toughest of applications. The tip of the Aggre-Gator is fused welded to the shank and made of hardened steel. Tapping threads and this makes installation fast and easy, despite the strength of the metal. They take the same size bit as a regular tapcon (referred by blue screws). Aggre-Gator is coated with silver-colored Stalgard® GB, a Galvanic Barrier, to protect aluminum components from accelerated corrosion when in contact with 300 series stainless steel. The gimlet point provides quick starts and makes Aggre-Gator anchors an ideal choice for treated, wood-to-wood applications.


Aggre-Gator Applications

Aggre-Gator tends to be used on exposed anchoring in coastal and wet areas. This means that Elco Fasteners can be used in water plants or locations with extended exposure to salt water.  Aggre-Gator is the best fastener when it comes to corrosion resistance and surpasses any tapcon on the market. You can also apply these 300 series stainless on aluminum enclosures, hurricane shutters, windows, awnings, and thresholds.

Aggre-Gator can also be used for curtain wall, window wall support, stone facade support and ACQ-treated wood. You won’t find a better, easier-to-install or more reliable 300 series stainless steel anchor for your toughest construction applications than Aggre-Gator bi-metal concrete anchors.
