The wood screw looks similar to a bolt or screw, but differs in thread pitch and thread height. Different grades of steel are used for different types of wood screws. For use in unfavorable conditions (moisture, snow, ice, high or low temperature), suitable steel grades are selected, and the products are additionally treated: coated with zinc by electroplating or hot-dip methods, passivated or phosphated, or given reflective coatings. Wood screws are also made from A2 stainless steel or A4 acid-resistant steel. All fasteners of this type must comply with GOST and the international standards DIN, ISO.
