DIN 968 Black Cross Recessed Pan Head Tapping Screws With Collar are a specific type of self-tapping screw that adheres to the German Industrial Standard (DIN) 968. These screws are designed with a black finish for corrosion resistance and a cross recess for ease of installation with a screwdriver. The pan head provides a low profile and a large bearing surface, which can help prevent the material from sinking or cracking, especially in softer materials.
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:
Black Finish: Offers corrosion resistance, which is suitable for outdoor applications or in environments where moisture is present.
Cross Recessed: Allows for easy installation with a common screwdriver, reducing the risk of the screwdriver slipping off during installation.
Pan Head Design: Provides a large bearing surface, which helps prevent the material from sinking or cracking, especially in softer materials.
Self-Tapping: Capable of creating their own threads in a predrilled hole, eliminating the need for pre-tapping, which saves time and effort.
Collar or Washer: The collar can distribute the load over an even larger area, reducing the risk of material deformation and providing a secure grip.
Scope of Application
Automotive Industry: For assembling interior trim panels, components, and body panels where a secure grip and a flush finish are required.
Construction and HVAC: Ideal for fastening metal roofing, wall paneling, and ductwork where a strong connection without pre-drilling is needed.
Electrical and Electronics: Secures components in electrical enclosures and control panels, as well as in the assembly of electronic devices where a low-profile appearance is desired.
Furniture and Cabinetry: Assembles wooden or composite materials in furniture and cabinetry, providing a secure and durable connection with a neat appearance.
Signage and Display: Used in the assembly of signs and displays where a flush finish is important for a clean look.
Machine and Equipment Assembly: In machinery and equipment assembly where a strong connection is needed, and the screw head should not protrude.
