Description
Product Overview
The VCN217-CNK Self-Locking Indexing Plunger With Rest Position is a high-performance industrial positioning fastener purpose-built for rapid, repeatable indexing and secure workpiece fixation, engineered to prevent locking position shifts caused by lateral force in high-cycle industrial operations. Designed for professional industrial purchasers and manufacturing enterprises requiring precise, reliable positioning for frequent equipment adjustments, this spring loaded indexing plunger delivers consistent locking performance, intuitive operation, and long-term durability in demanding industrial environments. As a knob-type self-locking indexing plunger, the VCN217-CNK features full stainless steel construction for both the pin and threaded body, paired with a corrosion-resistant stainless steel spring, ensuring uncompromising performance in harsh operating conditions. Its integrated rest position design enables stable pin retraction and locking via 90-degree knob rotation, eliminating the need for continuous manual holding and streamlining repetitive indexing workflows.
Key Features & Industrial Performance Advantages
Self-Locking Rest Position Design for Streamlined Workflows
The VCN217-CNK knob type indexing plunger incorporates an innovative self-locking rest position mechanism: rotating the knob 90 degrees locks the pin in the retracted state, freeing operators from continuous manual holding during workpiece changeovers or equipment adjustments. This design drastically reduces operator fatigue and improves efficiency for high-cycle indexing, positioning, and locking operations in industrial production lines.
Premium Corrosion-Resistant Full Stainless Steel Construction
Unlike standard indexing plungers with mixed-material components, the VCN217-CNK features a fully stainless steel build for the pin, threaded body, and internal spring, delivering exceptional resistance to corrosion, rust, and wear in humid, chemical-exposed, or outdoor industrial environments. This material selection ensures consistent performance through hundreds of thousands of actuation cycles, minimizing downtime and replacement costs for industrial operations.
Anti-Lateral Shift Design for Reliable Positioning
Engineered with a reinforced pin structure and precision-machined threads, this rest position indexing plunger effectively eliminates locking position displacement caused by lateral impact or vibration, a common pain point in standard positioning fasteners. This makes it ideal for high-vibration industrial equipment, precision fixtures, and automated machinery where unwavering positional accuracy is critical.
