Drill tail wire, also known as the self-tapping self-drilling screw, is an innovative fastener with a uniquely crafted design, engineered to perfection.
1, Definition and Characteristics
Definition: The drill tail screw is ingeniously crafted with a drill-tail or pointed-tail design at its end, skillfully engineered to drill, tap, and secure itself into setting or base materials without any auxiliary processing.
• Features: Seamlessly integrates drilling, tapping, and locking functions, significantly enhancing construction efficiency; possesses superior toughness and holding power compared to ordinary screws, ensuring long-term stability without loosening; designed for convenience, it completes drilling and tapping in a single, efficient operation.
2, Purpose:
The drill tail wire is predominantly utilized for securing color steel tiles within steel structures and is versatile enough to fix thin sheet materials in simple construction projects. However, it is not suitable for direct bonding and fixation between metal surfaces.
3, Classification and Materials
Classification: Based on their purpose and shape, drill tail screws are categorized into cross groove pan head, cross groove countersunk, cross groove semi-countersunk, hexagonal flange surface, and hexagonal flange self-drilling self-tapping screws, offering a variety of options for diverse fastening needs.
