The Post Nut Kwik Bolt II concrete anchors consist of a carbon KWIK BOLT II AND POST NUT KWIK BOLT II CONCRETE (ASTM A 29 Grade 11L41) or stainless (ASTM A276 Type ANCHORS 304) steel stud and post nut. The threaded end of the stud is fabricated to accept a threaded post nut with an outside 1.0 EVALUATION SCOPE diameter equal to the nominal diameter of the stud. The post Compliance with the following codes: nut has a countersunk head configuration.
