Grade 4.8 bolts are made of medium carbon steel with around 0.15%–0.25% carbon content, and are manganese, phosphorus, and sulfur alloyed for better machinability and performance. These bolts have a tensile strength of 400 MPa and yield strength of 320 MPa, providing consistent performance in moderate-load applications. With their even strength-to-flexibility ratio, they are suited to use in applications that do not require high-tensile resistance but need consistent structural support. Easy to install and easy to fabricate, Grade 4.8 bolts conform to international mechanical standards for safety and reliability in a variety of engineering applications.
4.8 grade bolts have universal application in construction, general engineering, automotive assembly, and agricultural machinery because they are moderately strong with high versatility. They can be used to attach non-bearing elements in buildings, exterior cladding systems, and architectural fittings on the interior. For the automotive and equipment industry, these bolts are appropriate for non-critical assemblies with moderate stress. Their cost-effectiveness, accessibility, and conformity to international standards render them a favorite among large-scale projects where strength and flexibility are crucial. Grade 4.8 bolts provide predictable, long-term fastening performance in moderately demanding conditions.
