Screw-ST4*12-Hexagon socket, flat round head, sharp end, self-attack

The Screw-ST4×12 hex-socket fastener is a compact, high-precision self-tapping screw designed for clean, confident joins in metal, plastic, and wood. With a hex drive, a flat round head, and a sharp tip, it behaves like a dedicated partner for quick-in, secure-out assemblies without the need for pre-threading in many materials.

Why this screw stands out

• 
  Hex-socket drive for precise torque: The hexagon socket offers strong engagement with minimal cam-out, making it easier to drive in tight spaces with consistent results.
• 
  Flat round head for a sleek finish: The rounded profile sits flush or just below the surface, delivering a tidy, professional look on enclosures, panels, and brackets.
• 
  Self-tapping, sharp point: The sharpened tip cuts its own thread as it enters the material, reducing installation time and eliminating the need for tapped holes in softer substrates.
• 
  Compact ST4×12 geometry: A 4 mm drive diameter with a 12 mm length fits small-to-medium assemblies, from electronics enclosures to furniture brackets, where space is at a premium.

Ideal uses and practical applications

Designed for quick, reliable fastening in projects where a neat appearance matters, this Screw-ST4×12 is well-suited for:

• Electronics or device enclosures and protective housings
• Metal or plastic brackets, supports, and mounting plates
• Furniture assembly where a low-profile, flush finish is desirable
• Workshop and hobby builds involving small equipment or chassis covers

Installation tips for best results

• Choose the right Allen key size that fits the hex socket snugly to minimize slippage and over-torque.
• For hard materials, consider a light pre-hole or pilot bore to guide the screw and reduce resistance.
• Align the fastener straight to the hole to ensure the self-tapping tip engages cleanly and the head seats evenly.
• Drive at a steady pace with even pressure; stop once the head is flush with the surface to avoid over-tightening.
