Thread and drill integration: Combines the functions of drill and thread to complete drilling, tapping and tightening in one operation.
High efficiency: Fast installation speed, especially suitable for large-scale assembly and construction.

How to use:
No pre-drilling required: Self-drilling screws can drill and tap directly on the material without pre-drilling.
Power tools: Usually use an electric screwdriver or drilling tool for installation to give full play to its high efficiency.
Application scenarios:
Metal structures: Widely used in the connection of steel structures, such as the fixing of steel frames, steel plates and steel accessories.
Roofs and walls: In construction projects, self-drilling screws are used to fix metal roofs, wall panels and guardrails.
Home appliance manufacturing: Used to fix metal and plastic parts of home appliances, providing a reliable fastening effect.
