Expansion Joint Pin

An expansion joint pin is a type of fastener used to secure two pieces of material together. It is typically used in applications where the two pieces of material need to be able to move independently of each other, such as in bridge construction or in the construction of large buildings. The pin is inserted through a hole in one piece of material and then secured in place with a nut or other fastener on the other side. Expansion joint pins are typically made from steel or other strong metals and are designed to withstand the forces of expansion and contraction.
