ABSTRACT OF THE DISCLOSURE A pull type fastener including a tubular sleeve and an elongated pin having a disposable pull portion at one end thereof with the sleeve having an enlarged pin head and a shank , a helically splined portion on the pin shank having ridges and grooves and adapted to engage a preselected portion of the sleeve shank bore to move the sleeve material into the spline grooves . The degree of interference between the splines and the sleeve shank , and the relative hardness ratio of the pin to the sleeve being designed such that the sleeve material will flow into the spline grooves without radially expanding the sleeve into interference with the bore of the workpieces being fastened. The result being that until the moment of clamp up the sleeve will rotate relative to the pin along the helical splines at a minimum pull force, then at clamp up a momentary and substantially increased torsional force resulting from the sleeve rotation being arrested assists in severing the pin from the pull portion thereof.
