Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws are engineered to address common industrial challenges such as vibration-induced loosening and corrosion in harsh operating conditions. The UNC coarse thread design facilitates quick assembly and provides excellent resistance to cross-threading, while the Class 3A thread fit ensures precise alignment in machined components. The flanged head distributes clamping force evenly, protecting soft materials and maintaining joint integrity under dynamic loads. Ideal for heavy machinery, automotive systems, and precision equipment, these screws deliver reliable performance where high tensile strength and corrosion resistance are critical to operational safety and longevity.
Specification Summary & Compliance
This socket head cap screw features a 1/4"-20 UNC thread with Class 3A fit for tight tolerance applications. Manufactured from alloy steel with Rockwell C39 hardness, it meets stringent performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
