Abstract: A method for forming a 360 degree integral skin handle in a thermoplastic part for use in automotive trim products includes the steps of forming a mold with a partial recess closed by a removable plug and thereafter selectively directing heat from a first source through the mold and from a second source through the plug to form a completely closed, curved, heated tube surface and thereafter casting thermoplastic material against the curved, heated tube surface to fuse and cure a layer of material thereon in the form of a tube skin segment which is releasable from the mold when the plug is removed. Apparatus for practicing the method includes a mold with a recess therein and a plug is supported on the mold for movement into a position for closing the tube surface and into a demolding position for releasing the molded part.

Abstract: A recessed drive socket in a fastener or the like, is driven by a mating, drive tool received within the socket. The socket cavity has a multilobular cross-section defined by an alternating annular series of adjacent socket flutes and socket lobes extending parallel along a general central axis from an entrance opening into the cavity circumscribed by a peripheral support collar. Each socket lobe is truncated by a guide surface inclined from the opening at a radially outer edge of an adjacent socket flute into the cavity to form a tool clearance recess portion of the guide surface which defines the radial outer edge of the adjacent flute.

Abstract: A method for forming a self-drilling screw. The self-drilling screw formed by this method stabilizes the screw during the hole drilling step of driving the screw and produces a precisely dimensioned hole for receiving the threaded portion of the screw. The method of forming the self-drilling screw starts with providing a screw blank having a head end and a tip. A driving head is formed on the head end and a drilling portion is formed on the shank distal the head end. Two longitudinally extending flutes are formed on the drilling portion of shank from the tip towards the head end. Each flute includes a working edge and a formed trailing edge. The working edges and the formed trailing edges of the two flutes are respectively diametrically opposed on the shank. A formed trailing diameter measured across the diametrically opposed formed trailing edges is greater than a working diameter measured across the diametrically opposed working edges.
