GB/T 1011-1986

GB/T 1011-1986 specifies the dimensions, technical requirements, and marking of truss head rivets used for permanent mechanical fastening in applications requiring a low-profile, broad bearing surface. It is primarily applied in the assembly of metal structures, machinery, and equipment where rivets are driven or pressed to join components, such as in automotive, aerospace, and general engineering contexts. The standard ensures interchangeability and reliability in static load-bearing joints where the rivet head must distribute load over a larger area to prevent material deformation.
