A4-70 Stainless Steel Partially Threaded Hex Head Screws Left-Hand Threaded Hex Bolts
Products Description
These A4-70 stainless steel screws are suitable for fastening machinery and equipment. Tighten them by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening.
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.
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.
Screws that meet ASME or ISO (formerly DIN) specifications comply with these dimensional standards.
