ABSTRACT:
An anchor is provided that is inserted into a bore in a cementious member, the bore having a side wall. A tensioning head is connected to the leading end of the stem and when the stem is moved the tensioning head moves with the stem. The outer surface of the tensioning head flares generally outwardly from the trailing end to the leading end of the tensioning head. The anchor also has an expansion sleeve, and the stem can move longitudinally through the expansion sleeve when the expansion sleeve is held in a fixed position, and the tensioning head pushes upon the expansion sleeve, causing it to flare outwardly. The expansion sleeve is provided with first and second grooves that assist the expansion sleeve in expanding without splitting.
