S-92140A104 0.188" ID x 0.75" OD Oversized Washers

Key Features & Benefits at a Glance

• Enhanced corrosion resistance from the black-oxide steel finish, extending service life in demanding environments.
• Precise load distribution with a 0.75" outer diameter, reducing surface pressure and preventing material damage.
• Secure fit for No. 8 screws due to the 0.188" inner diameter, minimizing loosening from vibration.
• Consistent thickness (0.120-0.130") ensures reliable performance and uniform clamping force in assemblies.
• Compliance with RoHS 3 and REACH standards guarantees safety and environmental responsibility for global supply chains.
• Durable steel construction provides excellent strength and longevity for repetitive industrial use.
• Inch-system compatibility simplifies sourcing and replacement in standard measurement-based applications.

Professional Applications & Engineering Value

This black-oxide steel flat washer is engineered to address common industrial challenges such as fastener corrosion and joint failure. The black-oxide surface treatment offers superior protection against rust and wear, making it ideal for applications in machinery, automotive, and outdoor equipment where moisture exposure is a concern. Its precise dimensions—0.188" ID for a snug fit on No. 8 screws and 0.75" OD for effective load spreading—help prevent bolt head embedment and distribute stress evenly, reducing the risk of assembly fatigue. By using these inch-system washers, engineers can achieve reliable, long-lasting connections in demanding environments, supported by compliance with international environmental standards for safe integration into global projects.
