• Features: Integrating drilling, tapping, and locking, greatly saving construction time; Compared with ordinary screws, drill tail screws have higher toughness and holding force, and will not loosen even after being combined for a long time; Easy to operate, drilling and tapping can be completed in one go.
2, Purpose:
Drill tail wire is mainly used for fixing color steel tiles in steel structures, and can also be used for fixing thin sheet materials in simple buildings. However, it cannot be used for direct bonding and fixation between metals.
3, Classification and Materials
Classification: According to their purpose and shape, drill tail screws can be divided into 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, hexagonal flange self drilling self tapping screws, etc.
