ABSTRACT:
An improved collapsible threaded anchoring device for securing items to a plate-like workpiece is an insert having an upper head portion adapted to engage the working face of the workpiece, an annular cylindrical sidewall which is collapsible and adjacent to the head portion, and a threaded shank portion. The head portion, the collapsible sidewall portion and the shank portion are integrally formed. The improved insert device is adapted for securing to a plastic plate-like workpiece. The improvement comprises a noncylindrical, noncollapsible collar having a cross-sectional width not less than the shank or sidewall portion and interposed between the head portion and the sidewall portion. The collar has an axial thickness slightly greater than the nominal thickness of the plastic workpiece.
