Description
Product Overview
Self-locking spring plungers from VEICH are precision-engineered industrial positioning components, also widely recognized as knob-type indexing pins, manual locking locating pins, and quick-change spring loaded plungers. Designed with an ergonomic red nylon handle and full stainless steel core construction, this series of stainless steel self-locking indexing plungers delivers exceptional locking stability and repeatable positioning accuracy for demanding industrial operations. Available in both fine thread (CN series) and coarse thread (MCN series) configurations, these plungers are tailored for professional industrial purchasers, fixture manufacturers, and automation equipment integrators seeking reliable positional locking solutions.
Key Features & Industrial Performance Advantages
Precision Self-locking Mechanism for Zero Accidental Disengagement
Our red handle self-locking spring plungers integrate an advanced spring-loaded locking structure with precision-machined plunger-to-hole fit, delivering an industry-leading indexing accuracy of up to -0.002mm. The self-locking design ensures stable positional retention even under high vibration, impact, or continuous cyclic operation, eliminating the risk of unexpected unlocking and costly production downtime.
Premium Material Build for Extended Service Life
The threaded shell, locating pin, and internal spring are all manufactured from high-grade stainless steel, while the ergonomic handle is made of durable Nylon 6. This material combination delivers outstanding corrosion resistance, wear tolerance, and a service life exceeding 100,000 operating cycles. The original surface finish maintains dimensional stability in extreme operating temperatures ranging from -50°C to 200°C, with optional IP65 protection available for harsh industrial environments.
Modular Configurations for Flexible Industrial Adaptation
This series of fine and coarse thread indexing plungers offers a wide range of standard sizes, including M8, M10, M12, and M16 thread diameters, with customizable plunger stroke, pin diameter, and knob color options. The one-pull-and-twist operation enables rapid locking and unlocking, cutting positioning time by over 80% compared to traditional fastening components and significantly boosting production line efficiency.
