Anchor bolt for anchoring by compound mass, and method of manufacturing the same

摘要

An anchor bolt has locking elements arranged over a part of the outer surface and formed as radially projecting lugs which are spaced circumferentially and axially from one another. Therefore a good mixing of a compound mass and reduction of the driving-in resistance is obtained. Therefore the outer diameter measured over the lugs of the anchor bolt can be matched approximately to the diameter of the drilled hole. Simple and inexpensive manufacture of the anchor bolt can be provided by powdered metal injection molding method using a system of binders with subsequent removal of the binders and sintering.
