Product Description

       Product introduction

Product Introduction

Self-tapping screws are a type of fastener that can be driven into a material without the need for a pilot hole. They are commonly used in woodworking, metalworking, and construction. These screws have a sharp tip and a thread that cuts into the material as it is driven

Self-Tapping Screw - High-Efficiency Fastening, No Pre-Drilling Required

A self-tapping screw is a high-performance fastener with built-in cutting or forming threads, specifically designed for quick installation. It can create a secure connection directly in materials such as metal, plastic, and wood without the need for pre-drilling or using nuts. Its unique thread design and pointed tip significantly enhance installation efficiency, making it suitable for applications in automated production, building and decoration, electronic equipment assembly, and home repairs. 
**Core Advantages:**
1. **Drill-free Design**: The tip features cutting edges (Type A/B) or thread-forming (Type C) structures, capable of penetrating materials and simultaneously forming matching threads, saving time and tool costs.
2. **High-strength Materials**: Made from carbon steel, stainless steel, or alloy steel, and treated with heat, zinc plating, Dacromet, or phosphating, offering both corrosion resistance and durability.
3. **Diverse Thread Types**: Double lead threads (for faster installation), wide pitch threads (for soft materials), and fine threads (for enhanced vibration resistance), catering to various working conditions.
4. **Wide Compatibility**: Compatible with multiple head designs (cross recess, hex head, and Torx head) and driving tools, including electric screwdrivers and manual wrenches. 
**Technical Parameters:**
- **Thread Type**: Type A (Coarse Cutting Thread), Type B (Fine Cutting Thread), Type C (Form Thread).
- **Diameter Range**: M2 to M12, Length 10mm to 200mm (Customized specifications available).
- **Surface Treatment**: Galvanized (Corrosion Resistant), Dacromet (High Temperature Resistant), Nickel Plated (Conductive), etc.
- **Certification Standards**: Compliant with international standards such as ISO 1478 and DIN 7500, and some models have passed RoHS environmental protection certification. 
**Typical application scenarios:**
- **Metal sheet connection**: Quick assembly of air conditioner casings, chassis, and metal frames.
- **Plastic part fixation**: Electronic product casings, automotive interior parts, and household plastic products.
- **Wood and composite materials**: Installation of light wood structures and composite material boards.
- **Outdoor facilities**: Weather-resistant fastening of guardrails, signboards, and solar panel supports. 
**Installation Recommendations:**
- Select the type of screw based on the hardness of the material (prefer cutting type for hard materials and forming thread type for soft materials).
- Ensure that the screw axis is perpendicular to the workpiece to avoid skewing and thread damage.
- Apply appropriate torque to prevent overload breakage or material cracking. 
Why Choose Self-Tapping Screw? **
With the convenience of "plug and play" and outstanding load-bearing performance, Self-Tapping Screw has become an ideal fastening solution in both modern industrial and civil fields. Whether it is large-scale production or small-scale maintenance, it can significantly improve efficiency and reduce costs.
