I claim the ornamental design for a thread end attachment fixture for tubular stock material, as shown and described.
FIG. 1 is a top perspective view showing my new design, parts shown in broken lines illustrating the environment of the fixture on the end of a tube member and forming no part of the claimed design.
FIG. 2 is a front elevational view of the threaded end attachment fixture of FIG. 1.
FIG. 3 is a side elevational view taken from the left in FIG. 2.
FIG. 4 is a side elevational view taken from the right in FIG. 2.
FIG. 5 is a rear elevational view taken from the opposite direction in FIG. 2.
FIG. 6 is a top plan view as viewed from the top in FIG. 2; and,
FIG. 7 is a bottom plan view as viewed from the bottom in FIG. 2.
The broken line showing in FIG. 1 is for environmental purposes only and forms no part of the claimed design.
