ABSTRACT:
A T-slot bolt sleeve for retaining the head of a conventional bolt in the T-slot of a machine tool table. The sleeve has a lower base block portion which slides in the main portion of the T-slot, and a neck portion which extends upwardly from this so as to ride in the relatively narrow entrance slot. There is a recess in the bottom of the base block for receiving the head of the bolt, and the shank of the bolt passes through a bore which extends upwardly from this. This holds the bolt in an inverted position so that the threaded end extends upwardly from the table for attachment of a nut or other fitting. The bottom of the base block is provided with a planar bearing surface which supports the assembly against side-to-side rocking as this is slid through the T-slot. The invention permits ordinary bolts of various lengths to be used in place of conventional T-nuts or T-bolts.
