A Spacer creates a precise distance or gap between two objects. The spacer is designed to fit over fasteners. The size and shape of a steel spacer can vary depending on its intended use, but they are typically manufactured to very tight tolerance to ensure accurate spacing between components. Spacers can be coated or heat treated to enhance their properties.

Attributes:
• Provides accurate alignment between components, ensuring that they are properly spaced and positioned.
• Made from high-strength steel to provide durability and resistance to wear and tear.

Applications:
