1. DIN 3121: DIN stands for “Deutsches Institut für Normung,” which translates to the German Institute for Standardization. DIN 3121 is a German standard that specifies the dimensions and technical requirements for square drives used in tools and accessories. It ensures compatibility and interchangeability between tools and attachments with the same square drive type.
2. Form F and H: These are specific forms or shapes of square drives defined within the DIN 3121 standard.
   • Form F is typically used for hand-operated tools.
   • Form H is often used for power tools.

   The choice between Form F and H depends on the application and the type of tool being used. For instance, Form H square drives are more common for power tools due to their increased load-bearing capacity.

3. ISO 1174: ISO stands for the International Organization for Standardization. ISO 1174 is an international standard that, similar to DIN 3121, specifies the dimensions and technical specifications for square drives used in tools and accessories. It ensures global compatibility and interchangeability of square drives, making it easier to use tools and attachments from different manufacturers together.
