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.

1. A multi-component metallic housing for a fluid comprising:a first metallic component defining a cavity that includes a set of internal threads; a second metallic component having an outer surface with a set of external threads mated to said internal threads such that said first component and second component are attached to one another and define a fluid cavity; at least one of said first metallic component and said second metallic component includes a fluid transfer passage opening to said fluid cavity; said set of internal threads including a first internal thread and a last internal thread; said set of external threads including a first external thread and a last external thread; and at least one of said first internal thread, said last internal thread, said first external thread or said last external thread being uniform.
