Product Description
Blue & White Galvanized One-Way Support Carbon Steel Hexagonal PCB Gasket
Rust-proof support column with superior triple-layer protection combining surface treatment, structural design, and functional properties.
Core Advantages
Triple Protection Technology
Surface treatment, structural design, and functional properties combine to outperform nylon isolation columns, bidirectional columns, and black zinc columns for industrial batch fastening requirements.
Advanced Blue-White Zinc Coating
Carbon steel substrate enhanced with premium electro-galvanizing:
  • Cost-effective rust and corrosion resistance - neutral salt spray test reaches 48-96 hours
  • Superior performance in indoor, dry outdoor, and humid environments
  • Costs only 1/3-1/2 of 304 stainless steel isolation columns
Durable Coating Adhesion
Excellent bonding with carbon steel substrate prevents peeling and scratching during installation and disassembly. Moderate hardness withstands friction and impact for extended service life.
Versatile Installation Options
One-way structure adapts to various requirements:
  • External thread one-way (screws into base plate to support upper plate)
  • Internal thread one-way (fixes upper plate with screws to isolate base plate)
  • External teeth with polished rod end (precise support without thread interference)
Recommended Solutions
Complete Blue-White Zinc Fastening System
Blue-white zinc one-way isolation column + cross-groove pan head screw + flat gasket combination enhances rust resistance, connection reliability, installation efficiency, and customer value.
Precision Equipment Solution
Blue-white zinc one-way isolation column with nylon anti-loosening gasket provides rust-proof, anti-loosening, and substrate protection for precision applications.
Substrate Compatibility
Ideal for carbon steel substrates, metal plates, and circuit boards. For plastic substrates, recommend matching blue-white zinc tapping screws for reliable connections.
