Fasteners are wildly used in buildings, automobiles, ships, aircraft, machinery, furniture and other products. Screws that meet ASME or ISO (formerly DIN) specifications comply with these dimensional standards. Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance. Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head. Metric screws are also known as A2 stainless steel screws. Black-oxide screws have a black appearance. Good after-sale service, all questions will be replied within 12 hours.
