VCN522.1 Carbon Steel Self-locking Type Mini Spring Plunger

 Carbon steel Spring Plunger

●Product Introduction
  This is a carbon steel locking spring pin, consisting of a carbon steel housing and an internal spring-loaded pin . Manufactured from high-quality carbon steel with quenching and surface anti-rust treatments-nickel plating, it is an industrial fastener integrating mechanical locking and elastic telescoping functions. Driven by an internal spring, the pin retracts and extends, and locks/unlocks quickly via the housing’s slot without additional tools.

●Structural Features

Carbon Steel Advantages: Carbon steel offers high strength and rigidity, capable of withstanding large shear forces and loads. It costs less than stainless steel, making it suitable for scenarios with low corrosion resistance requirements.

Locking Elastic Telescoping: Equipped with a high-elasticity spring assembly, the pin retracts and extends automatically. Once inserted into the hole, it mechanically interlocks via the slot to resist vibration-induced loosening, ideal for high-vibration mechanical components.

Easy Operation: The pin retracts for unlocking when pressed, and locks automatically when released. Assembly and disassembly can be completed without tools, significantly improving fitting efficiency.

Anti-Rust Treatment: Surface zinc/nickel plating provides protection against rust in general dry or mildly humid environments, extending service life.

●Typical Applications

General Machinery: Positioning of transmission components in machine tools and textile equipment; quick locking of equipment access doors/protective covers.

Automotive & Construction Machinery: Fixing of automotive interior parts; connection of small components in loaders (non-core corrosion-resistant areas).

Furniture & Storage Equipment: Fixing of industrial shelf layers; locking of metal toolbox doors.

Home Appliance Manufacturing: Quick assembly of housing components in large appliances (e.g., washing machines, air conditioners).
