Types of Spring Plunger
The spring plungers produced by our company mainly include the following types:
Ball Nose Threaded Spring Plunger
The ball nose threaded spring plunger consists of three main parts: a spring, a ball (also called a steel ball), and the plunger body. The spring provides the necessary force, while the ball serves as the moving contact point, and the plunger body holds all the components together to ensure smooth operation.
Long Nose Spring Plunger
The long-nose spring plunger is a mechanical fastener that is designed for precise positioning and secure fastening. with its extended nose, allowing it to reach deep into components for a reliable fastening. The plunger consists of a spring and a plunger body, where the spring provides the force to hold parts together, and the long nose ensures a firm connection.
Flanged Threaded Spring Plunger
The flanged thread spring plunger is a mechanical component that combines flange mounting and ball head contact. It contained a flanged base, plunger body, spring, and a steel ball. This allows it to handle high loads while providing precise positioning and buffering.

Applications of Spring Plunger
Automotive Industry
Spring plungers are used in the automotive industry for tool positioning, workholding, and fixture locking. These plungers help ensure that parts remain securely in place during assembly, machining, or quality control processes.
Aerospace Industry
In the aerospace industry, precision is critical. Spring plungers are used in tooling and positioning systems, ensuring that parts remain in alignment during assembly, inspection, and testing.
Industrial Machinery
Spring plungers are used extensively in industrial machinery, particularly in workholding and positioning systems. They are commonly found in CNC machines, milling machines, and lathes, where they help securely hold workpieces in place during operations.
Consumer Electronics
In the consumer electronics industry, spring plungers are used in the assembly and testing of small electronic components. They help secure and position components while preventing any accidental movement during the assembly or testing phases.
Materials Used in Spring Plungers
Stainless Steel
Stainless steel is a popular material for spring plungers because of its corrosion resistance, durability, and strength. It is ideal for applications in harsh environments, including wet or chemical exposure.
Advantages: Stainless steel plungers resist rust and corrosion, making them perfect for use in marine environments, food processing, and aerospace.
Carbon Steel
Carbon steel is another common material used for spring plungers. Although it does not have the same corrosion resistance as stainless steel, it is more cost-effective and provides excellent strength.
Advantages: Strong, durable, and economical, making it suitable for applications where cost-efficiency is important.
Disadvantages: More prone to rust and corrosion when exposed to moisture or harsh chemicals.
Zinc Alloy Plating
Zinc alloy plating is often used to coat carbon steel or stainless steel spring plungers, providing additional corrosion protection.
Advantages: Provides a cost-effective corrosion-resistant coating, suitable for mildly corrosive environments.
