Introducing a practical, pre-owned fastening solution built for reliability: cross recessed countersunk head tapping screws in carbon steel. Sized ST2.9x9.5, these self-tapping screws are designed to cut their own threads in soft metals and certain plastics, delivering a clean, flush finish with every drive. This listing represents a used batch that’s ready to bring value to your non-structural, everyday assemblies.

Key features

• 
  Drive type: Cross recessed (Phillips) for consistent seating with common hand and power tools.
• 
  Head style: Countersunk, providing a flush, snag-free surface once installed.
• 
  Material: Carbon steel, offering solid strength for routine fastening tasks.
• 
  Size: ST2.9x9.5 — a precise combination of diameter and length suitable for thin metal sheets and light-duty joints.
• 
  Self-tapping design: Taps its own threads, reducing pre-drilling steps in compatible materials.
• 
  Condition: Used—priced with consideration for resale and ideal for non-critical projects where appearance matters less than function.

Ideal uses and scenarios

• Electronics enclosures, control panels, and instrument housings where a low-profile, secure fastener is needed.
• Cabinetry, light metal shelving, brackets, and automotive trim where a flush finish improves aesthetics and safety.
• DIY projects and repairs that require reliable metal-to-metal or metal-to-plastic fastening without pre-tapping.

Why choose these for your project

• 
  Fast, flush assemblies: The countersunk head sits level with the surface, reducing snagging and improving overall look.
• 
  Versatility in materials: Suitable for thin sheet metal, certain plastics, and light metals where self-tapping action is beneficial.
• 
  Cost-conscious option: A used batch that delivers practical performance and value for non-critical applications.

Installation tips

• Match the pilot hole size to the material to optimize thread formation and prevent stripping.
• Apply steady torque and avoid over-tightening to maintain thread integrity and prevent damage to softer materials.
• Since these are self-tapping screws, they perform best in materials that allow the screw to cut cleanly; for harder metals, consider pilot holes and appropriate torque control.
