A method of manufacturing a threaded fastener form tool, the method comprising the steps of:
- preparing a feedstock of powdered metal and binder;
- heating and injecting the feedstock into a mold having an over-sized, negative image of the threaded fastener form tool;
- hardening the feedstock in the mold to form a green part;
- removing the green part from the mold;
- debinding the green part to form a debound part;
- and
- sintering the debound part to form a densified part having at least the near net shape of the threaded fastener form tool.
