Abstract: A pulling head that can be used with a wide range of fasteners and power tools having different stroke lengths and/or power ratings. The pulling head has a set of internal jaws which has serrations that are configured to grip a wide range of fastener types and sizes. The effective stroke of the pulling head is determined by the power tool to which it is engaged, rather than by the structure and design of the pulling head. The pulling head preferably has two jaws and a jaw follower with a leading surface which provides two beveled surfaces. As a result, the trailing surface of the jaws need not be conical, thereby providing that the jaws need not be machined after they are cast, thereby providing a very low cost manufacturing solution.
