Product Description
Product Overview
This product is a hexagon head drill tail self-tapping screw, made of carbon steel, with the core feature that the surface hardness reaches Rockwell C scale 25 (HRC25) and is coated with "Luxiu Bao" protective coating. Its drill tail tip can drill holes, tap threads and complete fastening on metal materials such as thin steel plates and aluminum alloy plates like a drill bit, without the need for pre-drilling and tapping, which greatly improves the installation efficiency in metal structure connection.
Core Advantages
-
Integrated Drill and Tap Function: The unique drill tail design can directly drill holes and form threads on a variety of metal substrates, eliminating the pre-drilling process and saving installation time.
-
Optimized Installation Hardness: HRC25 hardness balances material toughness and penetrability, which can effectively drill through the substrate and avoid brittleness and breakage due to excessive hardness.
-
Efficient Installation and Driving: The hexagon head type can be installed and disassembled efficiently with high torque using wrenches, sockets or electric tools, adapting to large-scale construction needs.
-
Excellent Corrosion Protection: "Luxiu Bao" coating provides far superior corrosion resistance than ordinary galvanizing, extending the service life in outdoor and harsh environments.
Applicable Industries
-
Metal Building and Enclosure Systems: Installation and fixation of color steel plate roofs, walls and steel structure sandwich panels.
-
Air Conditioning and Ventilation Ducts: Assembly and connection of ventilation equipment such as galvanized air ducts, angle iron flanges and fan boxes.
-
Automotive Components and Carriage Manufacturing: Fastening of truck carriage plates, passenger car skins and automotive component brackets.
-
Container and Prefabricated House Manufacturing: Quick connection of container roof panels, wall panels, prefabricated house frames and plates.
-
Solar Photovoltaic Supports: On-site installation of photovoltaic panel pressure blocks and guide rails, support beams and columns.
-
Animal Husbandry and Agricultural Facilities: Construction and maintenance of metal structures such as livestock sheds, grain depots and agricultural greenhouses.
-
Industrial Equipment Enclosures and Covers: Fastening of thin metal plates such as control cabinet shells, machine protective covers and sound insulation plates.
Warm Tips
-
Please select the appropriate screw length according to the total thickness of the materials to be connected (usually it is recommended that the thickness of a single layer of plate ≤ 5mm).
-
When installing, please use suitable electric tools and adjust the appropriate speed and torque to ensure that the drill tail completely penetrates and forms effective threads.
-
If the "Luxiu Bao" coating is scratched during installation, the scratched area still has a certain cathodic protection effect, but the overall protection performance will be reduced.
