Hexagon Self-Drilling Screw is a self-tapping screw with a hexagon head and hexagon socket drive design that is commonly used for joining metal, wood, or other materials. It features a self-drilling function that eliminates the need for pre-drilling and allows for direct drilling and complete fastening of holes in the material, making it ideal for efficient construction and industrialized production.
Main features of hexagonal drilling wires
Hexagonal head design:
Hexagonal heads can be quickly installed with wrenches, sockets or power tools (e.g. impact drivers), providing higher torque for high-strength fastening.
The head is usually larger, providing better pressure capacity and preventing the screw from sinking into the material.
Self-drilling feature:
The tip of the drilling wire is designed in the shape of a drill bit, enabling it to drill and tap holes directly into metal, wood or plastic, eliminating the need for pre-drilling steps and improving work efficiency.
Material & Surface Finish:
The material is mostly high-strength steel or stainless steel, with high hardness and tensile strength.
The surface is usually galvanized, phosphated or Dacromet treated to improve rust and corrosion resistance.
Thread design:
Threads are categorized into coarse and fine threads, coarse threads are suitable for soft materials (e.g. wood, plastic) and fine threads are suitable for hard materials (e.g. metal).
Some of the drilled ribbons have double thread design, which can cut into the material faster and increase the tightening force.
Wide application:
Suitable for the connection of metal plates, steel structures, aluminum alloys, wood, plastic and many other materials.
Commonly used in construction, steel structure, roof installation, fence building, machinery and equipment.
