ABSTRACT OF THE INVENTION This invention relates to fastening devices, e.g., rivets, bolts, etc. which are fabricated from a thermotropic liquid cry- stalline polymer and which contain up to about 50% by weight of a filler material. The fastening devices are characterized by a shear strength of at least about 15,000 psi (e.g., 15,000 to 75,000 psi and higher), a tensile strength of at least 20,000 psi (e.g., 20,000 to 150,000 psi and higher), a linear coefficient of thermal expansion which is compatible with the materials to be fastened and which ranges from about -3.0 to 3.0 X 10-5 (in/in°C). The fastening devices of this invention exhibit extremely high chemical resistance to a variety of deleterious materials. The fastening devices also exhibit a highly oriented skin. The ther- motropic liquid crystalline polymer utilized has an inherent vis- cosity of between about 1.0 and about 15 dl./g. when dissolved in a concentration of 0.1 percent by weight of pentafluorophenol at 60°C and may be fabricated from a wholly aromatic polyester, an aromatic-aliphatic polyester, a wholly aromatic poly(ester-amide), an aromatic-aliphatic poly(ester-amide), an aromatic polyazometh- ine, an aromatic polyester carbonate, etc. and mixtures thereof.
