    • A screw - plastic part unit in which the plastic part can be a guide having a tapered bottom end for fitting into a countersink to center the tip end of the screw in the countersink and also can have at least one cut-out portion at its top end to facilitate fracturing of the guide as the screw is threaded into a base member. In one embodiment the screw has a thread between its head and tip end which extends to near the tip end leaving a clear area between the thread end tip end and the part of plastic material molded around the screw clear area in which there can be a circumferential groove or rib finto or over which the plastic part is molded to better hold the part to the screw. In another embodiment fins extend into the part hole to hold the screw by an interference type fit.
    • 螺钉塑料部件单元,其中塑料部件可以是具有锥形底端的引导件,其具有锥形底端,用于装配到埋头孔中,以将螺钉的尖端中心在埋头孔中,并且还可以在其顶部具有至少一个切口部分 以便当螺钉拧入基座构件时促进导向件的压裂。 在一个实施例中,螺钉在其头部和尖端之间具有螺纹,其延伸到靠近尖端,在螺纹端部末端和围绕螺纹透明区域模制的塑料材料部分之间留有清晰区域,在该区域中可以具有周向 凹槽或肋鳍,或塑料部分模制在其上,以更好地将部件保持在螺钉上。 在另一个实施例中,翅片延伸到零件孔中以通过干涉型配合来保持螺钉。
