The din7985 cross-slotted pan head antitamper screw under GB818 is a screw with antitamper function, and its design includes a pan head and cross slots for easy installation and removal with a Phillips screwdriver. These screws are characterized by high preload and good anti-loosening properties, and are suitable for applications that require reliable fixing and are not easily loosened.

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:

Anti-loosening performance: the special design makes the screws not easy to loosen when subjected to vibration or shock, which improves the reliability of the connection. High strength: usually made of high-strength materials, able to withstand large preload. Easy to install: The cross slot design allows the screws to be quickly installed and removed using a standard Phillips screwdriver.

Scope of Application

Mechanical assembly: In mechanical equipment, used to fix components to prevent loosening due to vibration or shock. Building Structures: In building structures, used to connect structural components to ensure long-term stability. Electronic equipment: Used in the housing or component fixing of electronic equipment to ensure the stability of the components.
