An "articulated bolt" refers to a type of mechanical fastener that allows for movement between the two components it is joining, similar to how joints in a human body allow for movement. This is typically achieved through the use of ball joints or other types of hinges.

In the context of stainless steel, an articulated bolt would be made from this corrosion-resistant metal, which is often used in environments where durability and resistance to rusting are critical. Stainless steel can also enhance the aesthetic appeal of a construction due to its sleek and shiny finish.

However, it's important to note that 'articulated bolts' are not a standard term in engineering or construction terminology, so they might not be readily available or easily identifiable on the market. You may need to consult with a specialized hardware supplier or engineer to get the specific product you're looking for.

Typically, stainless steel is used for bolts because it offers excellent strength and durability, especially when exposed to harsh environments. It is used in a variety of applications such as marine structures, architectural elements, chemical processing equipment, and many more.

If you're referring to a specific type of stainless steel bolt designed for articulation or movement, it could potentially be a specialty item like a swivel bolt or a hinge bolt, but these would likely require custom manufacture or special order.
