The drill tail wire, an innovative marvel in fastening technology, is also widely recognized as a self-tapping, self-drilling screw. This uniquely engineered fastener boasts a special design that's tailor-made to meet the most demanding construction needs.
1, Definition and Characteristics
Definition: A drill tail screw is ingeniously crafted with a drill tail or pointed tail shape at its end. This allows it to seamlessly drill, tap, and lock into the setting material or base material without any need for additional steps or auxiliary processing.
• Features: This remarkable fastener combines drilling, tapping, and locking all in one streamlined process, significantly reducing construction time. Compared to ordinary screws, drill tail screws showcase superior toughness and holding power, ensuring a secure fit that resists loosening even after prolonged use. User-friendly in design, they allow for drilling and tapping to be accomplished effortlessly in a single motion.
2, Purpose:
The drill tail wire is predominantly utilized for the secure fixing of color steel tiles within steel structures. It also serves as an excellent solution for fastening thin sheet materials in straightforward building 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 various types, including 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.
