DIN 84 specifies slotted cheese head screws, which are widely used in mechanical assemblies, electrical applications, and general fastening tasks. These screws feature a cylindrical head with a slotted drive, making them easy to install and remove with a flathead screwdriver.
Key Features of DIN 84 Screws
- Head Type: Cylindrical cheese head with a flat top
- Drive Type: Slotted (compatible with flathead screwdrivers)
- Thread Type: Metric coarse thread
- Material Options: Available in steel (plain, zinc-plated), stainless steel (A2, A4), brass, and other corrosion-resistant materials
- Sizes: M1.6 to M20
Applications of DIN 84 Screws
DIN 84 screws are commonly used in:
- Electrical Engineering: Fastening components in electrical panels and devices.
- Mechanical Assemblies: Used in machinery where a cylindrical head is preferred.
- Automotive Industry: Securing components with precise fastening requirements.
- General Industrial Applications: Found in manufacturing and construction projects.
