Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head.
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.
Screws that meet ASME, or ISO (formerly DIN), or DIN specifications comply with these dimensional standards.
