The coating has been tested to extreme standards, including 1,000 hours of salt spray resistance, to hold up in wet and outdoor environments. Also known as black luster.High Fastener Strength Rating—About 25% stronger than medium-strength steel washers, these are commonly used when fastening components in valves, pumps, and motors.
