Description
Product Overview
VCN215-CN hand-retractable plungers (also known as knob-type indexing pins, manual indexing pins, or handle-style positioning pins) are industry-leading precision mechanical positioning components, engineered exclusively for industrial enterprise clients, precision machinery manufacturers, and automation solution providers. Built with a premium stainless steel core and durable aluminum knob handle, this series of stainless steel spring-loaded indexing plungers delivers rapid, repeatable, high-accuracy positioning and locking performance for diverse industrial scenarios. Designed for manual pull-and-twist operation, these plungers enable seamless engagement and disengagement of the precision pin from locating holes, streamlining workpiece positioning, clamping, and release workflows in high-demand production environments. Available in standard thread diameters from M10 to M20, the VCN215-CN aluminum knob retractable plungers are compatible with most mainstream industrial fixture and equipment designs.
Key Features & Industrial Performance Advantages
Premium Corrosion-Resistant Material Construction
Every critical load-bearing component of the VCN215-CN stainless steel indexing plungers – including the threaded shell, positioning pin, internal spring, and lock nut – is manufactured from high-grade stainless steel, delivering exceptional corrosion, wear, and rust resistance. The ergonomic handle is crafted from lightweight, high-strength aluminum, ensuring comfortable long-term operation while maintaining structural integrity in harsh industrial settings.
High-Precision Indexing & Stable Locking Mechanism
Equipped with a precision spring-loaded structure and tight-tolerance fit between the plunger pin and positioning holes, these hand-retractable spring plungers achieve a consistent indexing accuracy of ±0.1mm. The integrated indexing locking mechanism delivers stable, vibration-resistant locking performance, eliminating accidental disengagement and ensuring consistent positioning quality across high-volume production runs.
Extended Service Life & Extreme Environmental Adaptability
The hardened contact surfaces and heavy-duty stainless steel construction deliver a service life exceeding 100,000 operation cycles, minimizing replacement frequency and unplanned downtime for industrial operators. The plungers support an operating temperature range of -50°C to 200°C, with optional IP65 protection available, making them suitable for extreme environments including high-temperature, high-humidity, and sterile cleanroom settings.
