GB/T 15-2013 specifies the dimensions, tolerances, and technical requirements for mushroom head nib bolts, which feature a flat rounded head and a nib (protruding key) under the head to prevent rotation. These bolts are primarily used in mechanical assemblies and structural connections where anti-rotation locking is required, such as in railway equipment, agricultural machinery, and heavy-duty fastening applications. The standard ensures interchangeability and reliability in manufacturing and quality control for these specialized fasteners.
