KB-TZ2 anchors consist of a stud (anchor body), wedge (expansion elements), nut, and REPORT HOLDER: washer. The anchor(carbon steel version)''is illustrated in Figure 1.The stud is manufactured from carbon steelorAlS! HILT!,INC. Type 304 or Type 316 stainless steel materials. Carbon steel KB-TZ2 anchors have a minimum 5 pm (0.0002 inch) EVALUATION SUBJECT: zinc-nickel plating. The expansion elements for the carbon steel KB-TZ2 anchors are fabricated from carbon steel.The HILT! KWIK BOLT TZ2 CARBON AND STAINLESS expansion elements for the stainless steel KB-TZ2 anchors STEEL ANCHORS IN CRACKED AND UNCRACKED are fabricated from stainless steel. The hex nut for carbon CONCRETE steel conforms to ASTM A563-04.Grade A.and the hex nut for stainless steel conforms to ASTM F594. 1.0 EVALUATION SCOPE The anchor body is comprised of a high-strength rod Compliance with the following codes: threaded at end and a tapered mandrel at the other end. el 2018,2015,and 2012 International Building Cerde'`=(IBC) The tapered mandrel is enclosed by a three-section expansion element.The expansion element movement is 2018, 2015, and 2012 International Residential-Codee restrained by the mandrel taper and by a collar.The anchor (IRC) is installed in a predrilled hole with a hammer.When torque For evaluation for compliance with the National Building is applied to the nut of the installed anchor.the mandrel is Code of Canadae(NBCC),see listing report ELC-4266 drawn into the expansion element,which is in turn expanded For evaluation for compliance with codes adopted by' the against the wall of the drilled hole.
