The drill tail wire, fondly referred to as the self-tapping self-drilling screw, stands out as a cutting-edge fastener celebrated for its unique and innovative design.
1, Definition and Characteristics
Definition: The drill tail screw is ingeniously crafted with either a drill tail or a pointed tail shape at its end. This enables it to be directly drilled, tapped, and securely locked into the setting material or base material effortlessly, without necessitating any auxiliary processing.
• Features: Seamlessly integrates the drilling, tapping, and locking processes, significantly reducing construction time. Boasting superior toughness and exceptional holding force, these screws surpass ordinary screws as they remain securely fastened for extended periods without loosening. Furthermore, their simplicity of operation allows for drilling and tapping to be achieved in a single, efficient step.
2, Purpose:
This versatile drill tail wire is predominantly employed for fastening color steel tiles in robust steel structures. Additionally, it serves as an ideal solution for securing thin sheet materials in simple buildings. However, it's not suitable for direct bonding and fixation between metals.
3, Classification and Materials
Classification: Drill tail screws are categorized based on their purpose and shape. They include cross groove pan head self-drilling self-tapping screws, cross groove countersunk self-drilling self-tapping screws, cross groove semi-countersunk self-drilling self-tapping screws, hexagonal flange surface self-drilling self-tapping screws, and hexagonal flange self-drilling self-tapping screws, among others.
