Swedge Bolts or Swedge Rods are an alternative form of anchor bolt most commonly used in the DOT and bridge industries. They are also commonly used when the footing space is limited for an embedment.
A swedge bolt is threaded on one side with indentations on the other to enhance the “grip” of the part in concrete. Swedge bolts are manufactured by adding the indentations or “dimples” into the round bar by a press or similar machine to the non-threaded side of the part. The indentations are never to be “cut” into the rod as that would decrease the strength of the part. The configurations of the indentations vary from project to project depending, typically, on the engineer’s request.
Stel World GMBH manufactures swedge bolts in a variety of different materials but most commonly in F1554-55 and 105 as well as 316 and 304 stainless steels.
