Excerpt from ICC-ESR-1545 ( HSL-3 mechanical anchor ) showing the anchor diameter range . The diameter in bold text ( e . g . M10 , M12 , etc .) is the nominal diameter of the threaded element in the anchor . The outside anchor diameter (“ Anchor O . D .”) corresponds to the diameter of the external sleeve . The outside sleeve diameter is used to calculate V b
