●Product Introduction
This stainless steel black oxide single-bead ball head locking pin is a precision mechanical connection component. Constructed from stainless steel and finished with black oxide (passivation) treatment, it integrates a built-in single steel bead and spring mechanism to enable quick locking/unlocking. It replaces traditional bolts and rivets for temporary or permanent part positioning and fastening, serving as a core foundational element for efficient clamping and joining in industrial equipment.
●Structural Features
1.Material & Surface Performance
The main body is made of high-strength stainless steel; after black oxide treatment, it exhibits excellent corrosion resistance and wear resistance, suitable for humid and slightly corrosive working conditions. The single bead is crafted from high-hardness stainless steel (e.g., SUS440C) for stable locking performance.
2.Quick-Operation Design
A built-in spring drives the steel bead to retract: press the button to unlock (bead retracts), insert into the mounting hole, and release the button for automatic locking (bead snaps into the groove). This one-touch operation requires no tools, significantly improving assembly/disassembly efficiency.
3.Anti-Loss & Compact Structure
Equipped with a nylon cord/metal chain (as shown in the lanyard design) to prevent pin loss; the slim cylindrical structure and black oxide finish minimize installation space, fitting narrow equipment cavities.
●Typical Applications
1.Automation & Machine Tool Equipment
Used for quick clamping of production line fixtures, mold positioning blocks, and transmission components, ideal for scenarios requiring frequent disassembly.
2.Automotive & Marine Engineering
Applied to temporary fastening of automotive parts and marine equipment connectors, enduring vibration and seawater corrosion environments.
3.Electronics & Precision Instruments
Utilized for part positioning in PCB jigs and testing equipment, ensuring installation accuracy for delicate components.
4.Industrial Maintenance & DIY Scenarios
Suitable for temporary fixation during equipment repairs and quick adjustments of workholding fixtures, offering convenient operation and wide versatility.
