GB/T 831-1988 specifies the dimensions, tolerances, and technical requirements for slotted shoulder screws, which are fasteners with a cylindrical headless design and a slot for a screwdriver. These screws are primarily used in mechanical assemblies where a flush or low-profile fastening is needed, such as in precision instruments, electronic enclosures, and automotive components. The standard ensures interchangeability and reliable performance in applications requiring secure axial positioning without protruding heads.
