Swedged Rods

Swedged rods are also known as swedged anchor bolt or swedged anchor rod. It can be used an alternative to the headed anchor bolt, bent anchor bolt, epoxy anchor, or the threaded anchor rod. These rods see their usage in projects involving highways, especially alongside bridge bearings. The threaded end tends to project from the concrete and the embedded end comes with indentations that are pressed appropriately into the round bar so as to provide pull-out resistance. The AASHTO and the National Steel Bridge Alliance normally refer to these anchors as swaged anchor rods. Well, the indentations present on these rods are generally formed when the deformations are first pressed into the rod after which the steel is displaced rather than the steel being machined away in order to form dimples.


Baseline Bolts manufactures quality swedge anchor rods the diameter of which ranges up to 3″. We understand that some of our clients, engineers and agencies might require a different swedging pattern. To cater to their needs, BBI is equipped to completely accommodate any such requirements when it comes to swedge anchor rods. Provide us with a drawing of the pattern you require along with the indentation sizes and we will have it done for you in the most efficient manner.
