Abstract of the Disclosure The formation of minimized spangle galvanized steel sheet by impacting zinc powder particles on the molten zinc coating of the sheet to initiate crystallization is improved by adding a small amount of a hydrophobic material, preferably hydrophobic silica, to the zinc powder. The tendencies of the zinc powder to metallize and agglomerate are markedly decreased, leading to a more consistent minimized surface appearance, improved paintability and improved consistency of in-line temper rolling operation.

ABSTRACT OF THE DISCLOSURE A method and apparatus is provided for making a prevailing torque nut from a regular nut. The regular nut is placed between two anvil members, and a gap between the anvil members is first decreased so that they contact the nut on opposite sides. Then, the gap between the anvil members is further decreased by a preset amount, in order to permanently inwardly deform the nut. By making the preset amount a constant quantity, a plurality of nuts having sightly different outside and inside dimensions can be consistently deformed. A feature of this invention is the provision of a deformation apparatus which smoothly, progressively and consistently deforms a nut from one end to another. To accomplish this, the anvil members which cause the deformation have oblique working surfaces which taper toward each other, and which are adapted to bear against the nut over substantially the whole of the length of the nut, with the exception of an integral washer if such is present.
