S-97416A301 0.25" ID x 0.562" OD SAE Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance due to black-oxide steel construction, extending service life in humid or demanding environments
• Precise dimensional fit with 0.25" ID and 0.562" OD ensuring reliable alignment and load distribution for No. 12 screws
• Consistent thickness control (0.051-0.080") for uniform pressure distribution and reduced risk of fastener loosening
• SAE standard compliance guarantees interchangeability and reliable performance in inch-based mechanical assemblies
• Enhanced environmental safety with full RoHS 3 and REACH compliance, meeting strict international regulatory standards
• Durable steel core provides excellent load-bearing capacity and resistance to deformation under stress

Professional Applications & Engineering Value

These SAE flat washers are engineered to solve critical industrial challenges where corrosion resistance and dimensional precision are paramount. The black-oxide steel surface treatment creates a protective barrier against oxidation and chemical exposure, making them ideal for automotive assemblies, machinery frames, and outdoor equipment where moisture or chemicals are present. Their precise 0.25" ID and 0.562" OD dimensions ensure perfect compatibility with No. 12 screw sizes, preventing bolt hole misalignment and distributing clamp load effectively to protect sensitive surfaces from damage. The consistent thickness maintains uniform pressure across joint interfaces, reducing maintenance frequency in vibration-prone applications.

Specification Summary & Compliance

Manufactured to SAE standards with inch system measurements, these washers feature precise dimensional tolerances for reliable performance. The black-oxide steel construction meets industry specifications for corrosion protection. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptability for industrial applications.
