The thin thread profile enables fine‑tuning of the installation position, allowing engineers and technicians to achieve exact indexing and stopping points for a variety of machines and fixtures. This product is a core component for telescopic lock pins, widely used across machinery, engineering equipment, and workshop tool production lines.

Usage

Designed for versatility, the push fit ball nose plunger excels in applications where rapid positioning and secure locking are essential. It is commonly employed in CNC machines, assembly jigs, robotic arms, and custom fixtures where repeatable positioning reduces setup time and improves overall productivity. The self‑locking feature allows operators to pull the knob to retract the pin or push it in to lock the component, making adjustments swift and reliable. Because the plunger is made from stainless steel, it performs well in environments exposed to moisture, chemicals, or temperature fluctuations, ensuring long‑term performance without rust or degradation. Whether you are a machine shop technician, a manufacturing engineer, or a hobbyist building a precision rig, this plunger provides the confidence that parts will stay exactly where you need them.
