In-depth Overview of Double Headed Tooth Tip Tail Screws
The double headed tooth tip tail screw is a marvel of engineering, a uniquely crafted dual-headed fastener. It seamlessly combines the self-tapping prowess of the pointed tail with the robust T-shaped tooth fastening. Primarily, it excels at swiftly connecting and securing wood, plastic, or lightweight metal materials. Here's an exploration of its standout features and applications:
------
1, Essential Composition
1. Innovative Dual-End Design:
Pointed End: Equipped with a razor-sharp tip and self-tapping capability, this end effortlessly pierces through soft substrates like wood or plastic, negating the need for pre-drilling and streamlining your installation endeavors.
Mi-Shaped Tooth End: Featuring a Mi-shaped thread (cross groove), this end is perfect for rapid tightening with electric tools (such as screwdrivers), ensuring a reliable clamping force.
2. Composition and Finishing Touches:
Composition: Fashioned from standard carbon steel (Q235) and stainless steel (SUS304), delivering a harmonious blend of strength and resistance to corrosion.
Surface Finish: Options include zinc plating, blackening, or phosphating, all designed to bolster rust resistance and adaptability in moist conditions.

2, Core Capabilities
Rapid Self-Tapping: The pointed end efficiently penetrates soft materials like wood and plastic, reducing drilling steps and significantly boosting installation speed.
• Versatile Adaptability: The T-shaped tooth end seamlessly pairs with various tools (cross screwdriver, electric drill bit), ensuring a smooth tightening process and uniform force distribution.
Solid Connection: The dual end threads work in harmony to balance tensile and shear forces, preventing unwanted loosening and detachment, ideal for furniture and decor subject to frequent stress.

3, Ideal Applications
1. Furniture Assembly: Perfect for concealed connections in cabinets, drawer rails, and more, these screws penetrate wooden boards with their pointed ends and achieve a flawless finish with their square teeth.
2. Decorative Projects: Secure light steel keels, decorative panels, and more, meeting the high-demand fastening needs of wood or composite materials with finesse.
3. DIY Repairs: Ideal for light-duty scenarios such as home manual repairs or securing electrical enclosures, empowering any DIY enthusiast.

4, Installation Protocols
1. Selection and Compatibility:
Choose the screw length based on material thickness (e.g., M4/M6 specifications) to guarantee the pointed end fully penetrates and the square tooth end achieves sufficient screwing depth.
2. Step-by-Step Procedure:
• Insertion Phase: Align the pointed end vertically with the material, applying hand pressure or light taps to aid insertion and prevent misalignment or thread damage.
Tightening Phase: Use a cross screwdriver or power tool to rotate the square tooth end until the screw head is flush with the material surface, avoiding over-tightening to prevent cracking.
3. Important Considerations:
Pre-drill hard materials (like metal) with a slightly smaller diameter than the screw to enhance grip.
Conduct regular checks for corrosion or looseness in screw heads, promptly replacing damaged parts to ensure lasting connection stability.
