Abstract
A plastic screw anchor having legs each formed with a recess which provides the leg with good flexibility whereby the legs can easily deform during the insertion thereof into an aperture of a supporting plate and also provides a strong grip between the screw anchor and the supporting plate. A wing integrally formed on each leg prevents the screw anchor from coming out of the aperture after having once been inserted therein.
