Wedge Anchors Explained By An East Coast Distributor At Online Resource Page


Baco Enterprises Inc. answers the most common questions about wedge anchors and how they hold steel to concrete surfaces in a multimedia online resource guide.

A comprehensive guide to wedge anchors is live at the website of Baco Enterprises Inc. in Bronx, NY. A video, Q&A section, and other content explain the optimal uses for wedge anchors. The information will aid companies sourcing wedge anchors and other fasteners in the selection of materials, coatings, and sizes.


Builders use wedge anchors primarily to connect steel pieces to solid concrete. The anatomy of a wedge anchor includes a threaded rod, end clip, nut, and washer. Wedge anchors create a secure hold between materials due to the way the clip expands and grips the concrete. For this reason, these fasteners also go by the common names of expansion anchors, expansion bolts, or concrete bolts.

Wedge anchors are responsible for attaching pieces to structural columns and concrete pillars. They also have smaller scale uses, such as holding down industrial equipment to a concrete floor.

Common materials used to make wedge anchors include stainless steel, zinc-plated steel, hot-dipped galvanized steel, and carbon. When buying wedge anchors for an infrastructure, construction, or maintenance project, a company must consider the external conditions that the wedge anchors will be subjected to.

General exposure to the outdoors, like a parking lot or school yard, requires anchors that can resist moderate amounts of corrosive substances like rain and air pollution. Stainless steel or hot-dipped galvanized wedge anchors would serve well under such conditions. Environments that expose a structure to the sea, like at a dock or shipyard, benefit from the use of 316 wedge anchors that resist prolonged exposure to corrosive elements.

Due to their use in construction where earthquakes can occur, wedge anchors come in the categories of cracked and uncracked. Cracked concrete wedge anchors are engineered to cope with the stresses of seismic activity.

The wedge anchors resource page emphasizes the importance of predrilling holes for the fasteners to the correct diameter. Holes that are too large will result in the anchors coming loose.
