Stainless steel is useful for more than just a visual purpose. The main highlight would be the superior corrosion resistance, stopping unwanted issues like rusting. High heat resistance is also a big benefit, due to the way stainless steel is created, it can withstand an incredible amount of heat as opposed to a screw or socket made from standard steel. The only possible issue may be cost. However, a reliable and durable material will not only increase the longevity of the application, but also the sustainability.
