GB839 Straight Thread Screws, also known as Knurled Head Non-Stripping Screws, are screws with a knurled head and a straight thread (straight slot) drive slot. This design provides a good feel and easy manual operation, while the knurled head provides additional friction, making the screw less likely to slip out when tightened or loosened. The straight groove design allows the screws to be quickly installed and removed using a screwdriver.
Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.
Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.
Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.
Advantage:
GOOD FEEL: The knurled head design provides a good feel for manual operation.
ANTI-LOOSE PERFORMANCE: The knurled head provides extra friction and reduces the risk of screw slippage when tightening or loosening.
QUICK INSTALLATION: Straight groove design allows for quick and easy installation and removal.
AESTHETICS: The knurled head design gives the screw a more aesthetic appearance for applications where exposed screws are required.
Scope of Application
Machinery and equipment: In machinery and equipment, used to fix components, such as handles, hoods, etc. Furniture manufacturing: in the assembly of furniture, used to connect and fix parts, such as drawers, door panels, etc. Building decoration: in building decoration, used for fixing interior decorative panels, ceilings, etc. Electronic equipment: used in the fixing of housings or components of electronic equipment to ensure the stability of the components.
