Helpful Notes
- Grades: Common U.S. grades include Grade 2 (general), Grade 5 (medium strength), and Grade 8 (high strength). Stainless options (e.g., 18-8) preferred for corrosion resistance.
- Standards: Structural flat washers are typically ASTM F436. Socket, hex, and machine screws follow ASME/IFI dimensional standards.
- Compliance: Our CR+3 Zinc, CR+6 Zinc, Hot-Dipped Galvanized, Thermal Black Oxide, and Plain finishes are noted as RoHS compliant where relevant.
