A ball plunger screw is a mechanical fastener with a built-in spring and steel ball head, and is a type of spring plunger. Its structure consists of a threaded body, built-in spring, and steel ball protruding from the exterior. It is commonly used in industrial applications such as positioning, limiting, clamping, and fixing.
Key Features of the Ball Plunger Screw:
Compact Design: Resembles a screw in shape with standard threads, making it easy to install in threaded holes.

Excellent Ball Expansion: The ball can freely expand and contract under spring force, enabling precise elastic positioning.

Easy installation: No special tools required; simply screw it in for use.

Precise positioning: Suitable for mechanical components requiring frequent positioning or limiting, ensuring repeatable accuracy.

Common application scenarios:
Mechanical clamping fixtures and jigs positioning

Mould limiting and positioning holes

Adjustable positioning points in automated equipment

Stop devices for sliding components
