Professional Applications & Engineering Value

These 316 stainless steel SAE flat washers deliver exceptional value in corrosive industrial environments where standard fasteners fail. The marine-grade 316 stainless steel composition provides superior resistance to chlorides, chemicals, and extreme temperatures, making them ideal for marine equipment, chemical processing plants, and food processing machinery. The precise inch-system dimensions (0.344" ID × 0.688" OD) ensure perfect compatibility with 5/16" screws, while the controlled thickness variation maintains consistent clamping force in vibration-prone applications. These flat washers effectively prevent surface damage, distribute loads evenly, and extend service life in heavy-duty mechanical assemblies where reliability is critical.

Specification Summary & Compliance

Manufactured to SAE standards with precise inch-system dimensions: 0.344" inner diameter, 0.688" outer diameter, and thickness range of 0.051-0.080". These flat washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The 316 stainless steel construction provides excellent corrosion resistance without additional surface treatments, maintaining dimensional stability across various industrial applications.
