I claim the ornamental design for a tool for driving a fastener, as shown and described.
FIG. 1 is a front-top-right perspective view of a tool for driving a fastener;
FIG. 2 is a rear-top-left perspective view of the tool for driving a fastener of FIG. 1;
FIG. 3 is a front elevational view of the tool for driving a fastener of FIGS. 1-2;
FIG. 4 is a rear elevational view of the tool for driving a fastener of FIGS. 1-3;
FIG. 5 is a left side elevational view of the tool for driving a fastener of FIGS. 1-4;
FIG. 6 is a right side elevational view of the tool for driving a fastener of FIGS. 1-5;
FIG. 7 is a top plan view of the tool for driving a fastener of FIGS. 1-6; and,
FIG. 8 is a bottom plan view of the tool for driving a fastener of FIGS. 1-7.
The portions of the tool for driving a fastener shown in broken lines form no part of the claimed design. The dash-dash-dash lines are for the purpose of illustrating environmental structure and form no part of the claimed design.
