Professional Applications & Engineering Value

Engineered for demanding industrial applications, these socket head cap screws deliver critical performance where vibration resistance and structural integrity are paramount. The 18-8 Stainless Steel composition provides excellent corrosion resistance in manufacturing environments, chemical processing, and outdoor equipment, while the Class 3A thread fit ensures precise alignment in precision machinery and automated systems. The coarse UNC threading offers superior resistance to loosening under dynamic loads, making these fasteners ideal for heavy machinery, transportation equipment, and industrial automation where reliability cannot be compromised. The combination of high tensile strength and standard socket head profile allows for efficient installation in confined spaces without sacrificing performance.

Specification Summary & Compliance

This socket head cap screw features precision 1/4"-20 UNC threads with Class 3A fit for superior thread engagement and dimensional accuracy. Manufactured to ASME B18.3 specifications with complete compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The inch system measurements maintain consistency with North American industrial standards while the fully threaded design provides uniform stress distribution across the entire fastener length.
