*USED* Cross recessed countersunk head pointed tapping screws ST3.5*13 plated with blue and white zinc; K014

Discover a budget-friendly solution for precise, flush-fitting fastenings with these used Cross recessed countersunk head pointed tapping screws, size ST3.5×13, finished in blue and white zinc. Designed for quick metal/threaded assemblies, these screws combine a sharp pointed tip for self-tapping into thin metal with a low-profile countersunk head that sits neatly flush once installed. The blue and white zinc plating provides robust surface protection while maintaining a clean, professional look for your project.

Why these screws stand out

• 
  Self-tapping efficiency: The pointed tip creates its own pilot hole in soft to medium-thickness metals, speeding up assembly and reducing the need for pre-drilled holes.
• 
  Flush, low-profile finish: Countersunk head seats perfectly against the surface, delivering a clean, professional appearance in enclosures, chassis, or panels.
• 
  Reliable Phillips drive: Cross recessed (Phillips) drive minimizes cam-out and provides solid torque transfer for repetitive assembly tasks.
• 
  Durable plating: Blue and white zinc coating offers corrosion resistance and a uniform finish suitable for domestic, hobby, and light-industrial use.
• 
  Pre-owned value with proven usability: These are used screws, carefully selected for continued functionality, offering cost savings without compromising essential performance.

Ideal uses and scenarios

• Electronic enclosures, instrument housings, and small metal-box projects where a flush mounting is preferred.
• Light gauge sheet metal assemblies, brackets, and thin panels in hobby projects, small machinery, and DIY electronics.
• Budget-conscious refurbishments or spares where replacing the entire fastener set isn’t necessary.

Practical installation tips

• Use a Phillips screwdriver sized for ST3.5 screws to maximize grip and reduce the risk of slipping.
• For optimal self-tapping performance, work with metal in the 0.5–2.0 mm range; thicker materials may require longer screws or pre-drilling.
• A light touch and steady torque help prevent thread stripping, especially with used fasteners where some wear may exist.
• Inspect threads before reuse; if you notice significant wear or corrosion, consider retiring the screw and using a fresh fastener for critical assemblies.
