Hexagonal Self-Drilling Screws

Hexagonal self-drilling screws are an efficient and convenient fastener. This type of screw combines self-drilling and self-tapping functions. It can drill holes and form threads directly on the surface of the material without pre-drilling or tapping, which greatly improves construction efficiency.
Product features:
Diverse materials: Hexagonal self-drilling and self-tapping screws are usually made of stainless steel, such as 304, 410, 316L, etc., with excellent corrosion resistance and oxidation resistance, suitable for humid or harsh environments.
Complete specifications: The product covers a variety of specifications, such as M4 to M12, suitable for connecting plates of different thicknesses, including steel plates, color steel tiles, aluminum plates, etc.
Design optimization: The head is designed as a hexagonal flange head or flange head, providing a larger contact area and enhancing the fastening effect. At the same time, the threaded part is cold forged to ensure the strength of the tooth pattern and avoid damage due to frequent use.
Waterproof and rust-proof: Some products are equipped with rubber sealing rings or anti-corrosion coatings to effectively prevent rain erosion and corrosion and extend service life.
Hexagonal self-drilling screws can be used in a variety of scenarios such as building roofs, photovoltaic brackets, guardrails, etc., and are particularly suitable for engineering applications that require high strength and durability. Drilling and tightening operations can be completed with special power tools, without manual operation, saving labor costs.
Customized services can be provided for special needs, such as special length, coating treatment or washer design.
