Grade 60 Threaded Rebar
Our R6J Grade 60 Rebar is most often used in resin bolting or for anchor dowels. Depending on the application it may be more economical than Williams R61 Grade 75 All-Thread Rebar, however, the installer does not have the flexibility of a continuous workable thread. Williams offers threaded end rebar in the following sizes.
