Abstract
A tool for holding threaded inserts in a rotational mold includes a stud which projects within the mold cavity and which has a diameter substantially equal to the minor diameter of the threads of the insert. A spring loaded detent on the stud is received by the internal threads of the insert for holding the insert firmly against the inner wall of the mold yet permitting simple removal of the molded part. A retractor mechanism for using the tool with threaded inserts placed across the axis of removal of the molded part, is also taught.
