DIN 7981 is a standard that specifies the requirements for a specific type of screw. This standard outlines the dimensions, materials, and other technical specifications that the screw must meet in order to be considered compliant. The DIN 7981 screw is commonly used in various industries, including automotive, construction, and electronics. It is known for its self-tapping capabilities, which allow it to create its own threads when driven into a pre-drilled hole. This type of screw is designed to provide a secure and reliable fastening solution, making it a popular choice for many applications.
