A pin is a mechanical element used in various machines and devices that serves as a connector or rotating element. It can be made of various materials such as steel, stainless steel, brass or plastics, depending on the application and required strength.

Pin Features:

• Connector: A pin can connect two components, allowing their mutual rotational or translational movement.
• Pivot Point: In the case of hinges or joints, the pin acts as the axis of rotation.
• Security: Can be used to secure components from shifting or coming apart.

Maintenance and safety:

• Regular Inspections: Pins should be checked regularly for wear, corrosion and damage.
• Lubrication: Moving parts require regular lubrication to ensure smooth operation and reduce wear.
• Proper fit: The pins should fit properly into the holes to ensure a secure connection without play.
