Grade 8.8 Carbon Steel High-Strength Screws / Fasteners Key benefits High load capacity and reliability: Grade 8.8 carbon steel provides the strength needed for structural and dynamic applications, reducing risk of fastener failure under heavy or repeated loads. Durable and precise construction: Manufactured for dimensional accuracy and long service life, ensuring consistent fit and secure connections. Easy to machine and fabricate: Excellent machinability and good cold- and hot-workability speed production and on-site adjustments, reducing installation time and fitting complexity. Suitable for dynamic and safety-critical connections: High toughness and material integrity make these fasteners appropriate where vibration, impact, or cyclic loading occur. Material and performance Material: Grade 8.8 carbon steel (commonly known as high-strength screws). Mechanical attributes: High toughness, good cold and hot workability, and excellent machinability support reliable performance in demanding assemblies. Function: Designed to create secure, load-bearing connections in structural steelwork and industrial equipment. Typical applications (specific use scenarios) Steel frame construction: Girder-to-column connections in building frames where high-strength, load-bearing fasteners are required for structural integrity. Heavy equipment and cranes: Fastening heavy-duty crane beams and industrial equipment where dynamic loads and frequent movement demand durable, high-strength connections. Bridge and infrastructure components: Securing solid bridge beams and other transportation or infrastructure parts, including braking system mounts and other components that carry dynamic or safety-critical loads. Compatibility and usage notes Intended for use where grade 8.8 fasteners are specified; compatible with common structural steel components and assemblies following grade 8.8 specifications. Best used in bolted connections and assemblies designed for high-strength metric fasteners; ensure proper torque and installation procedures for peak performance. Select these screws when high toughness, reliable load performance, and good machinability are required for critical or dynamic structures.
