Application Summary AI generated
This standard specifies the mechanical properties, such as tensile strength and hardness, for bolts, screws, and studs made from fine grain non-heat treatment steel. It is applied in the manufacturing and quality inspection of fasteners used in mechanical systems, particularly where cost-effective, high-strength fasteners are needed without the additional heat treatment process. The standard ensures these fasteners meet performance requirements in automotive, construction, and general engineering applications.
