Blue Zinc Plated Carbon Steel One-Way S-Slot Security Screw – Tamper-Proof Design for Fence Panels

Blue Zinc Plated Carbon Steel One-Way S-Slot Security Screw – Tamper-Proof Design for Fence Panels

Product Overview

Our Blue Zinc Plated One-Way S-Slot Security Screw combines robust security with weather-resistant durability, designed for tamper-proof fastening of fence panels, gates, and outdoor structures. Featuring a one-way S-slot drive for anti-vandalism and a vibrant blue zinc coating for corrosion resistance, this screw ensures reliable performance in public spaces, residential fencing, and coastal environments. Crafted from grade 4.8/8.8 carbon steel, it delivers high tensile strength while deterring unauthorized removal.

Key Features

✅ Tamper-Proof S-Slot Drive

  • One-Way Installation: Install with a standard flat-head screwdriver; removal requires a specialized S-slot extractor tool (sold separately).
  • Anti-Theft Design: Prevents disassembly with common tools like pliers or coins, ideal for high-traffic or public areas.

✅ Blue Zinc Plating

  • Corrosion Resistance: Withstands rain, humidity, and salt spray, making it suitable for coastal or industrial environments.
  • Aesthetic Appeal: Vibrant blue finish adds a subtle visual deterrent while blending into outdoor fixtures.

✅ Carbon Steel Construction

  • Grade 4.8/8.8: 420–800 MPa tensile strength for heavy-duty use in wood, metal, or composite fence panels.
  • Self-Tapping Threads: Sharp point cuts through materials without pre-drilling, reducing installation time.

✅ Fence-Optimized Design

  • Low-Profile Head: Flat or pan head sits flush to deter tampering and prevent snagging.
  • Reusable: Maintains thread integrity if removed with the correct tool for maintenance or repairs.
