Application Summary AI generated
GB/T 5287-2002 specifies the dimensions, tolerances, and technical requirements for extra large series washers of product grade C. These washers are used in mechanical assemblies to distribute load over a larger area under bolts or nuts, particularly in heavy machinery, construction equipment, and structural steel connections where oversized clearance holes or soft materials require increased bearing surface. The standard applies to industrial fastening systems where precision is less critical (grade C), focusing on general engineering and maintenance contexts.
