Anchor bolt for anchoring by means of a grouting mass and its method of manufacture

摘要

The masonry fitting bolt has a pattern a protrusions (5) spaced over its outer shaft in an area which is to be inside the bored hole. The protrusions are spaced and orientated in such a way that the insertion of the bolt provides an even mixing of the bonding material which is introduced into the bore to cement the bolt into place. The protrusions are produced on the bolt by metal power moulding of the protrusions and the bolt. The protrusions are shaped to provide a cutting edge to clean the bore prior to fitting and have an offset array to provide a good grip and a good mixing effect. The leading end of each protrusion can be pointed for ease of insertion.
