Product Overview

The Double Headed Tooth Tip Tail Screw is a masterfully designed fastener, uniquely crafted to merge the self-tapping prowess of a pointed tail with the robust grip of T-shaped tooth locking. It's the go-to choice for rapid and secure attachment of wood, plastic, or lightweight metal materials.

🛠️ 1. Basic Structure

Dual End Differentiated Design:

• Sharp End: Featuring a razor-sharp tip with self-tapping capability, it effortlessly pierces soft substrates like wood or plastic, eliminating the need for pre-drilling and streamlining the installation process.

• Mi Shaped Tooth End: Equipped with a Mi-shaped thread (cross groove), ideal for swift tightening using power tools like electric screwdrivers, delivering a strong and secure clamping force.

Material and Treatment: Utilizes common carbon steel (Q235) and stainless steel (SUS304), with options for zinc plating, blackening, or phosphating to boost rust resistance.

🎯 2. Core Functions

Quick Self Attack: Pointed end penetrates soft materials smoothly, reducing drilling steps.
High Adaptability: Compatible with cross screwdrivers and electric drills for uniform force distribution.
Stable Connection: Dual end threads balance tensile and shear forces, preventing loosening in high-stress areas.

🏠 3. Application Scenarios

Furniture Assembly: Ideal for hidden connections in cabinets and drawer rails.

Decoration Projects: Used for attaching light steel keel and decorative panels to wood or composite materials.

DIY Repair: Perfect for light load applications and securing electrical enclosures.

📋 4. Installation Specifications

Selection: Match screw length to material thickness (e.g., M4/M6) for full penetration.
Insertion: Press vertically into the material to prevent deviation and thread damage.
Tightening: Rotate until flush with the surface; avoid overtightening to prevent material cracking.
Hard Materials: Pre-drill with a slightly smaller diameter for enhanced gripping force in metals.

Frequently Asked Questions

What materials are these screws made of?

These fasteners are typically manufactured from carbon steel (Q235) or stainless steel (SUS304) to provide high strength and durability.

Do I need to pre-drill holes before installation?

For soft materials like wood and plastic, the sharp self-tapping end eliminates the need for pre-drilling. However, for hard materials like metal, pre-drilling is recommended.

What surface treatments are available for rust prevention?

We offer several surface treatments including zinc plating, blackening, and phosphating to ensure excellent corrosion resistance in humid environments.

Can these screws be used with power tools?

Yes, the Mi-shaped (cross groove) tooth end is specifically designed for high-efficiency tightening with electric screwdrivers and power drills.

How do I choose the correct screw size?

You should select the screw length based on the thickness of your material to ensure the pointed end penetrates fully while the tooth end secures the piece tightly.

What industries are these fasteners suitable for?

They are widely used in the construction industry, furniture manufacturing, decoration projects, and for general home DIY repairs.
