A special bolt used in aircraft construction in which the shank is ground to a tolerance of +0.000, -0.0005 inch. Close-tolerance bolts are identified by a triangle around the mark on the bolt head that identifies the material of which the bolt is made. The shank of a close-tolerance bolt is not cadmium plated, but it is kept from rusting by a coating of wax or grease.
