Wedge Anchors In Galvanized, Zinc Plated, Stainless Steel, Expansion And Other Varieties
A wedge anchor is a type of expansion anchor that’s typically used to permanently anchor steel directly to solid concrete. Wedge anchors are actually a fastener assembly, which is comprised of a threaded rod that ends with a clip. This clip creates a secure installation and makes them particularly easy to identify compared to other anchors and fasteners.
Wedge anchors also include a nut and washer that are included as part of the total assembly. Wedge anchors are sometimes referred to as expansion anchors, expansion bolts, or concrete anchors. They are also sometimes called Trubolts, Kwik Bolts, Power Studs, and Wedge Bolts, however these names are specific to individual wedge anchor manufacturers.
Available Wedge Anchor Materials And Choosing Them
Wedge anchors come in varied materials and types. Zinc plated wedge anchors are among the most common. Other types include stainless steel wedge anchors, hot dipped galvanized steel and carbon wedge anchors. When choosing wedge anchors made from specific materials or with particular finishes, it’s important to consider the environmental and structural demands of the end installation. For example, in potentially corrosive, moist environments, such as those subjected to salt water or a variety of weather, stainless steel or hot dipped galvanized wedge anchors would be an optimal choice due to their corrosion resistance.
What To Know When Choosing Stainless Steel Wedge Anchors
Wedge anchors made from different grades of stainless steel also offer varying levels of corrosion resistance. 304 wedge anchors would be suitable for use in outdoor applications that are subject to only a moderate level of corrosive hazards, such as an urban playground or parking lot, while 316 wedge anchors would be better suited to a more corrosive environment, such as a dock or outdoor industrial facility. If corrosion is not a major concern, as in most indoor installations, then a zinc plated wedge anchor would suffice for such applications.
What Are Cracked And Uncracked Wedge Anchors
The terms cracked and uncracked have less to do with the general structure of a wedge anchor than where it’s to be used. Cracked and uncracked wedge anchors are specially made for installation in cracked and uncracked concrete, respectively. Cracked concrete certified wedge anchors are manufactured according to specific criteria, which ensures they can be used in areas where seismic activity is likely to occur.
Where Are Wedge Anchors Most Commonly Used?
Some of the most common places you’ll find wedge anchors are part of structural columns, concrete pillars, and precast footings. While wedge anchors are often used for structural applications, they can also be used to secure industrial hardware to a concrete floor, wall, or other surface. Wedge anchors might be used to fix a washing machine, boiler, or other appliance, firmly in place. They can even be used in stone and masonry work, such as a household brick wall or mantle.
Mistakes To Avoid When Installing Wedge Anchors
Wedge anchors should only be installed in solid surfaces and by predrilling a properly sized hole. It’s very important that the size of the hole, in which the wedge anchor is being installed, is properly sized to fit. One of the most common mistakes made when installing wedge anchors are making oversized installation holes. This can cause the installation to loosen and fail. It’s also important to thoroughly clean the installation hole and surface prior to installation. Dust and debris can compromise the integrity of a wedge anchor installation. Wedge anchors should not be used in structural material that isn’t solid, such as hollow brick.
Sleeve Anchors Vs. Wedge Anchors
If an anchor is needed for a hollow brick or other similar surface a sleeve anchor would be used in place of a wedge anchor. While the clip at the end of a wedge anchor serves to secure the fastener into a solid material, the addition of a metal sleeve on an aptly named sleeve anchor creates the tension and backing needed to secure the fastener within a hollow material. Like wedge anchors, sleeve anchors are meant to be permanent, non-removable fasteners.
Large Diameter Tapcons Vs. Wedge Anchors
Large diameter tapcons are similar fasteners to wedge anchors. They are also installed in holes that are pre-drilled within concrete or similar materials. While they resemble bolts structurally, the thread that runs the rod of the large diameter tapcon resembles saw teeth. The serrated structure serves to cut into concrete as the large diameter tapcon is being installed. This amounts to a strong and secure grip. It also allows for possible removal of the large diameter tapcon using a torque wrench.
Industrial Strength Alternatives To Wedge Anchors
While wedge anchors are a reliable and easy way to fasten steel to concrete, alternative fastening components and methods can be used. One of the most common alternatives is industrial epoxy. Using epoxy, as part of an installation process is typically more involved than the use of wedge anchors, however, use of epoxy isn’t limited to a specific size and length. Use of wedge anchors or epoxy is not always interchangeable; the best option will depend on the unique factors of a specific installation.
