Tighten these screws by turning them to the left; once fastened, they prevent loosening from counterclockwise motion. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
