摘要： An anchor bolt assembly of the type wherein expansion members are slidably mounted on an expansion portion of the bolt by means of a brace interconnecting the expansion members and passing over the bolt end. The expansion members have the shape of wings stamped together with the brace legs and its base from one piece of sheet material. The brace base engages the end face of the bolt. The wings collectively encircle the greater part of the circumference of the conical expansion bolt portion. Hook means formed by bent rear corners of rear wing parts extend beyond the bolt circumference in an outward-backward direction.
