What is the current code required geometry for a grade 60 #5 bar used in concrete masonry?
Table 6.1.8 in the current TMS 402-16 (current referenced edition by the 6 Ed FBC) call for Grade 60 reinforcing for a #3 through a #8 bar to have an inside bend diameter of 6 db and an extension of 12 db. For a #5 bar the tip of the extension would then be 15 db or 9.37" from the face of the bar.
