- Regulatory compliance meeting ASME B18.6.3, RoHS 3, and REACH standards for quality assurance and environmental safety
Professional Applications & Engineering Value
Engineered for industrial applications requiring both structural integrity and corrosion resistance, this rounded truss head slotted screw addresses common challenges in machinery assembly, electrical enclosures, and outdoor equipment. The 18-8 Stainless Steel material combined with a passivated finish provides lasting protection against rust and chemical exposure, while the UNC coarse thread and Class 2A fit ensure rapid installation and secure fastening in metal, plastic, or composite substrates. Its wide truss head offers increased bearing surface, preventing pull-through in softer materials and maintaining clamp force under dynamic loads, making it a reliable choice for heavy-duty and vibration-prone environments.
Specification Summary & Compliance
This screw features precise Class 2A thread fit with UNC 5/16"-18 coarse threading and right-hand thread direction, manufactured to ASME B18.6.3 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence. Dimensions include a 0.698" head diameter, 0.183" head height, and 2" fully threaded length, providing consistent performance across industrial fastening tasks.
