A chain-shaped pin is a fastener or connector that is typically used in applications requiring linkage or joining multiple components together, often in a chain-like configuration. It may be used for securing or connecting parts, or as a way to hold components in place while still allowing movement or flexibility.

Features of a Chain-Shaped Pin:

1. Shape and Design:

   • The term "chain-shaped" usually refers to a series of pins or a single pin designed to resemble a chain, or it may be a pin with a chain attached to it for easy removal or handling.
   • The pin may have a cylindrical, tapered, or specialized shape that allows it to be inserted into a hole and secured with a retaining mechanism.

2. Material:

   • Chain-shaped pins are typically made from metal (steel, stainless steel, or brass) or durable plastic, depending on the application’s load requirements and environmental conditions.
   • Often corrosion-resistant finishes like zinc plating or galvanization are applied for outdoor or industrial use.

3. Function:

   • It serves as a connecting or securing element, ensuring that two parts stay together without separating unintentionally.
   • Commonly used where easy insertion, removal, or adjustment is needed.
