S-96659A111 0.656" ID x 1.312" OD ASME B18.21.1 SAE Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 stainless steel construction ensures long-term reliability in harsh environments
• Precise dimensional fit with 0.656" ID and 1.312" OD provides optimal load distribution for 5/8" fasteners
• Enhanced durability through controlled thickness (0.074-0.121") maintains consistent performance under pressure
• Industry-standard compliance with ASME B18.21.1 guarantees mechanical integrity and interchangeability
• Environmental regulation adherence with RoHS 3 and REACH compliance for global supply chain compatibility
• Reduced maintenance requirements due to stainless steel's inherent resistance to rust and degradation
• Broad industrial applicability across SAE inch-system machinery and equipment installations

Professional Applications & Engineering Value

This 5/8" flat washer delivers critical engineering solutions where corrosion resistance and dimensional precision are paramount. The 18-8 stainless steel composition prevents galvanic corrosion and withstands chemical exposure, making it ideal for food processing equipment, marine hardware, and outdoor industrial applications. Its SAE designation and ASME B18.21.1 compliance ensure perfect compatibility with standard 5/8" fasteners, while the optimized 1.312" OD provides superior surface coverage to prevent embedding and distribute clamping forces evenly. The flat washer design effectively seals gaps and protects sensitive surfaces from abrasion, extending component lifespan in high-vibration environments.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 standards with inch-system dimensions: 0.656" ID, 1.312" OD, and thickness ranging 0.074-0.121". The 18-8 stainless steel construction meets mechanical property requirements for general-purpose applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted international distribution.
