Self-drilling and self-tapping screw with hexagonal flange face is a kind of multi-functional fastener, which has the characteristics of self-drilling and self-tapping. According to GB/T15856.4-2002 standard, hexagonal flange surface self-drilling self-tappingThe screw consists of a thread area and a hexagonal flange face of the same diameter. It is able to punch holes automatically and install itself on the substrate surface by self-tapping threading, eliminating the need for prefabricated holes and nuts.The construction efficiency is improved.
What are the characteristics of hexagonal flange self drilling and self tapping screws
1. Fast construction: hexagonal flange self-drilling self-tapping screw without pre-drilling and nut installation, only use a screwdriver or wrench to complete the tightening, greatly saving the construction time.
2, excellent pumping strength: hexagonal flanged self-drilling self-tapping screws are made of high-strength steel, and the thread design is reasonable, which can provide excellent pumping strength and ensure the reliability of fasteners during use
3, excellent anti-rust performance: hexagonal flange surface self-drilling self-tapping screws after galvanized or stainless steel surface treatment, has excellent anti-rust performance, in the use of the process can effectively prevent 1 rust, extend the service life of fasteners.
4. Wide range of application: hexagonal flange surface self-drilling self-tapping screws are suitable for the connection of steel, wood and other different substrates, widely used in construction, furniture, automobiles and other fields.
What are the application scenarios of hexagonal flange self drilling and self tapping screws
1. Construction field: Hexagonal flange self drilling self tapping screws are commonly used in steel structure construction, roof fixing, wall decoration and other construction. The characteristic of rapid construction can greatly improve project progress and construction efficiency.
2. Furniture field: Hexagonal flange self drilling self tapping screws play an important connecting role in furniture manufacturing. It can quickly fix furniture components, provide stable connections, and ensure the safety of furniture use.
3. Automotive field: Hexagonal flange self drilling self tapping screws are widely used in automotive manufacturing and repair. It can be used to fix car bodies and components, with good tensile strength and rust resistance, improving the safety and durability of cars.
4. Other fields: Hexagonal flange self drilling self tapping screws can also be used in electronic equipment, household appliances, mechanical equipment and other fields to meet the fastening needs in different fields.
