High-Precision Zinc-Coated Cylindrical Pin – Blue & White Plating for Hardware &

Product Description

Core Advantages

1. Superior Corrosion Resistance

   
   

   The blue-white zinc plating forms a robust barrier against rust, moisture, and chemical erosion. Tested to ASTM B117 standards, it can withstand 48–72 hours of neutral salt spray testing, providing long-lasting protection in humid, outdoor, or corrosive environments and significantly extending the service life of assembled products.
2. High Precision for Seamless Assembly

   
   

   Tolerances (typically ±0.02mm for diameter and length) are strictly controlled during production to ensure precise positioning and stable connection. Whether used as a spacer, locating pin, or load-bearing element, it minimizes assembly errors to the greatest extent and enhances the reliability of the overall product.
3. Structural Stability and Load-Bearing Capacity

   
   

   High-quality base materials such as carbon steel, stainless steel, or brass are available (customizable on demand), endowing the component with excellent mechanical strength. The solid cylindrical design enables uniform force distribution, making it suitable for scenarios requiring stable load-bearing, such as mechanical hinges and furniture connectors.
4. Long-Term Durability

   
   

   The combination of the base material and anti-corrosion plating allows the component to resist wear, scratches, and environmental damage. Even in high-frequency usage scenarios like automotive wiring harnesses and industrial tooling, it can maintain structural integrity for a long time.

Material and Manufacturing Process

• Base Material Options: Carbon steel (grades like 1010, 1020), stainless steel (grades like 304, 316), brass, or aluminum are available. Customization is supported based on strength, weight, and other requirements.
• Plating Process: The blue-white zinc plating is applied via professional electroplating technology, resulting in a uniform and smooth coating. It not only offers excellent corrosion resistance but also improves appearance consistency—ideal for "visible application scenarios" such as furniture hardware.
• Quality Control: Each batch undergoes plating thickness inspection (optimal protection requires a coating thickness of ≥8μm) and adhesion testing to ensure the coating remains intact under mechanical stress.

Multi-Industry Applications

• Automotive Manufacturing: For chassis assembly, interior part fixing, and wiring harness positioning.
• Machinery and Equipment: Suitable for precision alignment in fixtures, conveyor systems, and CNC machines.
• Furniture and Hardware: As stable spacers or connectors in cabinets, shelves, and decorative metal products.
• Electronics and Electrical: For component installation in enclosures, control panels, and PCB (Printed Circuit Board) assemblies.
• Molds and Tooling: For precise positioning of molds, punches, and cores.

Specifications and Customization Services

• Standard Sizes: Diameter range: 3mm–20mm; Length range: 5mm–50mm (length can be customized).
• Custom Options: Non-standard sizes, special platings (e.g., black zinc, nickel), and secondary processing (drilling, slotting, tapping, etc.) are supported to meet personalized design needs.

Quality Assurance and Logistics Services

• Certifications: Compliant with ISO 9001 quality management standards; RoHS/REACH material certifications can be provided on demand.
• Inspection Process: Each batch comes with inspection reports for dimensional accuracy, plating quality, and salt spray testing to ensure traceable quality.
• Packaging: Inner packaging uses anti-rust films/bags; outer packaging is sturdy cartons or pallets (custom packaging available for retail and bulk orders).
• Shipping and Lead Time: Air freight, sea freight, and international couriers (DHL, FedEx, UPS, etc.) are supported, covering Europe, the US, Asia-Pacific, and other global regions. Sample lead time: 3–5 days; Bulk order lead time: 10–15 days (adjusted according to order quantity).
