PROBLEM TO BE SOLVED: To provide a seizure preventive method for easily fixing a fastener to an assembly. SOLUTION: For example, a nail driven by a hammer, or a threaded nail or a screw screwed in a shaft joint, a nut or a building block, is cited as the fastener. In one embodiment, a composition includes a sufficient quantity of boron nitride to be applied to a contact surface of the fastener, and the fastener can be quickly fixed without causing seizure and/or frictional wear. An effective quantity of boron nitride powder composition is also applied to the contact surface of the fastener, that is, the pointed tip or a thread surface of a shaft part.
