Description of the Double Headed Tooth Tip Tail Screw
Our Double Headed Tooth Tip Tail Screw is a masterfully engineered fastener. It marries the precision-driven self-tapping prowess of a sharp tip tail with the steadfast grip of T-shaped tooth fastening. Primarily crafted for the rapid assembly and secure fixation of wood, plastic, or lightweight metal materials, its standout features and application insights are detailed below:
------
1. Core Structural Attributes
1. Dual End Differentiated Design:
Sharp End: Featuring a razor-like tip with superior self-tapping capabilities, this end pierces effortlessly into soft materials like wood or plastic. The need for pre-drilling is eliminated, streamlining the installation process impressively.
Mi-Shaped Tooth End: Equipped with a Mi-shaped thread and cross groove, it's perfectly suited for rapid tightening using electric tools like screwdrivers, delivering a reliable and stable clamping force.
2. Material Composition and Surface Enhancement:
Material: Constructed from robust carbon steel (Q235) or resilient stainless steel (SUS304), it offers an ideal balance of strength and corrosion resistance.
Surface Treatment: Options like zinc plating, blackening, or phosphating significantly boost rust resistance, making this screw adept in humid environments.

2. Core Functional Benefits
Quick Self-Attack: The pointed end efficiently penetrates soft materials such as wood and plastic, minimizing drilling steps and maximizing installation efficiency.
• High Adaptability: With its T-shaped tooth end compatible with various tools (cross screwdrivers, electric drills), it ensures a smooth tightening process and evenly distributed force.
Stable Connection: The dual end threading synergistically balances tensile and shear forces, effectively preventing loosening or detachment. Perfect for parts under frequent stress in furniture and decorative installations.

3. Diverse Application Scenarios
1. Furniture Assembly: Ideal for invisible connections in cabinets, drawer rails, and more. It pierces wooden boards with its pointed end and secures with square teeth for a flawless installation.
2. Decoration Projects: Fixes light steel keels, decorative panels, and more, meeting the fastener needs of wood or composite materials with efficiency.
3. DIY Repairs: Perfect for light-load applications such as home repairs or securing electrical enclosures.

4. Installation Specifications
1. Selection and Matching:
Choose screw lengths appropriate for material thickness (e.g., M4/M6 specifications). This ensures the pointed end fully penetrates while providing ample screwing depth at the square tooth end.
2. Step-by-Step Operation:
• Insertion Phase: Vertically press the pointed end into the material, use hand pressure or gentle taps to assist insertion, preventing deviation and thread damage.
Tightening Phase: Employ a cross screwdriver or power tool to rotate the square tooth end until the screw head is flush with the material's surface. Avoid over-tightening which could lead to material cracking.
3. Important Precautions:
For hard materials (e.g., metal), pre-drilling with a slightly smaller diameter than the screw is essential for enhancing the bite force.
Regularly inspect for corrosion or looseness in the screw head, and promptly replace any damaged components to ensure connection stability.
