ABSTRACT:
First and second mold members are fitted one within another and together define a first annular space for forming a discontinuous single thread in a thin-walled housing, as well as a second annular space coaxial and contiguous with the first annular space; the second space defines the thread on the interior wall of the housing in the form of teeth members for receiving a threaded member associated with a linear adjustment device used with an agricultural implement, such as a spreader.
