- Comprehensive compliance certification including ASME B18.3, RoHS 3, and REACH for global quality assurance
Professional Applications & Engineering Value
Engineered for demanding industrial environments where metal fasteners fail, this glass-filled nylon socket head cap screw solves critical engineering challenges. The non-conductive, non-magnetic properties make it ideal for electrical enclosures, while its chemical resistance prevents degradation in processing equipment. The 3/8"-16 UNC coarse thread configuration with Class 2A fit ensures reliable performance in vibration-prone applications, maintaining clamp force where standard fasteners loosen. With operational capability from -40° to 200°F, it provides consistent performance in thermal management systems, food processing machinery, and outdoor installations where temperature extremes would compromise metal alternatives.
Specification Summary & Compliance
This socket head cap screw maintains precise Class 2A thread fit per UNC standards with 3/8"-16 coarse threading and 2" fully threaded design. Manufactured to ASME B18.3 specifications for dimensional accuracy and performance reliability. Compliant with RoHS 3 (2015/863/EU) for hazardous substance restriction and REACH (EC 1907/2006) for chemical safety management, ensuring global regulatory acceptance for industrial procurement.
