S-90231A114 0.14" ID x 0.312" OD SAE Washers

Key Features & Benefits at a Glance

• Corrosion-resistant brass construction ensures long-lasting performance in humid or chemically aggressive environments, reducing replacement frequency.
• Precise 0.14" inner diameter provides a secure fit for No. 5 screws, minimizing loosening and vibration-related failures.
• 0.312" outer diameter with consistent thickness (0.025-0.040") distributes load evenly to protect surfaces and prevent fastener embedment.
• SAE standard compliance guarantees interchangeability and reliability in inch-system assemblies, streamlining procurement and inventory.
• REACH regulatory compliance assures safe use in industrial settings, meeting stringent environmental and health standards.
• Non-magnetic and spark-resistant properties of brass make these washers ideal for electrical and explosive atmosphere applications.

Professional Applications & Engineering Value

These brass SAE flat washers are engineered to address common industrial challenges such as galvanic corrosion, surface damage, and fastener loosening. The corrosion-resistant brass material prevents rust and degradation, making them suitable for marine, plumbing, and electrical enclosures where moisture is prevalent. With a 0.14" ID tailored for No. 5 screw size, they ensure precise alignment and uniform clamping force, reducing stress concentrations on assembled components. The SAE standard design and inch system compatibility facilitate easy integration into existing machinery and equipment, enhancing maintenance efficiency and operational reliability in mechanical systems.

Specification Summary & Compliance

This washer adheres to SAE standards with an inner diameter of 0.14", outer diameter of 0.312", and thickness ranging from 0.025" to 0.040", ensuring dimensional accuracy for No. 5 screw applications. Manufactured from high-quality brass, it complies with REACH (EC 1907/2006) regulations as of June 14, 2023, covering 235 SVHC, and is suitable for general industrial use where hardness is not rated but corrosion resistance is critical.
