Abstract: A method of reducing metallic debris in a multi-component metallic housing for a fluid comprises the initial step of providing a first metallic component that includes a portion with a circular cross section and defines part of a fluid cavity when mated to a second component. A set of threads are machined on the circular portion and includes full threads separated by a beginning partial thread and an ending partial thread. Next, a substantial portion of at least one of the beginning partial thread or the ending partial thread is removed. The removal step could be performed either before or after the threads are actually cut into the first metallic component. The present invention finds one potential application in the manufacture of fuel injector components.
