Hexagon Head Slotted Self-Tapping Screws for Multi-Material Applications
Key Design Feature: Integrated Drive & WasherProducts
Hexagonal head slotted self-tapping screws have an advantage due to the slots on their hexagonal heads, allowing for easy fastening on wood, plastic, and thin metal substrates - without the need for pre-drilling, thus simplifying the assembly process.
Material & Surface Treatment OptionsProducts
Material selection:
• 304/316 stainless steel: Resistant to corrosion and moisture, suitable for various humid environments.
• 1018/1045 carbon steel: Low cost, suitable for indoor dry environments.
• Alloy steel: Extremely high strength, suitable for assembly of various heavy machinery.
• Brass: Excellent electrical conductivity, suitable for electronic devices.
Surface treatment enhances durability:
• Zinc coating: Salt spray resistance of 48 - 96 hours
• Nickel coating: Anti-adhesion
• Black oxidation: Treatment improves lubricity.
Structural Optimizations for PracticalityProducts
The structural improvements include the use of hexagonal heads to achieve precise torque application, as well as an internal gasket that can evenly distribute the pressure – thus avoiding indentation on the soft substrate. The angles are also differentiated: for metal materials, the angle is 90° to 120° (favorable for efficient drilling); for wood/plastic materials, it is 150° to 180° (which can reduce cracking).
01
Lightweight metal processing
Suitable for fixing thin plate components in electrical cabinets, HVAC piping, and metal enclosure systems. Threads can be directly formed in pre-drilled holes of low-carbon steel, aluminum alloy, or galvanized thin plates without the need for tapping operations, thereby shortening the assembly time.
01
Automated production lines
Used for fastening lightweight components in automated lines, such as sensor mounting plates, small motor bases, conveyor belt side guards, and fixture auxiliary components. Particularly suitable for assembling non-bearing connection components of peripheral equipment for industrial robots.
01
Electrical and electronic equipment assembly
Used for fixing junction boxes, distribution panels, and small household appliance shells. Suitable for fastening thin plastic or metal components in electronic products, meeting the lightweight and compact design requirements of electronic devices.
