GB/T 19990-2005 specifies the technical requirements, dimensions, and mechanical properties for fixing bolts used to attach soil working elements (such as plowshares, tines, and blades) to agricultural tillage machinery. It is applied in the manufacturing, quality inspection, and replacement of bolts for soil-working equipment like plows, cultivators, and harrows to ensure secure fastening under heavy loads and abrasive field conditions. This standard is primarily used by agricultural machinery producers and maintenance engineers in China to standardize bolt interchangeability and reliability in tillage operations.
