S-90183A212 0.134" ID x 0.375" OD Washers for Blind Rivets

Key Features & Benefits at a Glance

• Enhanced corrosion resistance from zinc plating, extending service life in humid or industrial environments.
• Precise fit for 1/8" rivets with a 0.134" inner diameter, ensuring secure fastening and reducing installation errors.
• Optimal load distribution due to the 0.375" outer diameter, which helps prevent surface damage and loosening.
• Consistent thickness (0.057-0.067") provides reliable spacing and vibration dampening in assembled components.
• RoHS 3 & REACH compliance guarantees environmental safety and meets strict international regulatory standards for industrial use.
• Durable zinc-plated steel construction offers excellent strength and longevity for demanding applications.
• Wide compatibility with standard inch-system fasteners, simplifying inventory and procurement for various projects.

Professional Applications & Engineering Value

These zinc-plated steel flat washers are engineered to address common challenges in industrial assembly, such as corrosion-induced failure and uneven load distribution. The zinc plating provides a protective barrier against moisture and chemicals, making them ideal for outdoor equipment, automotive components, and machinery exposed to harsh conditions. With an inner diameter of 0.134" tailored for 1/8" rivets, they ensure a precise fit that minimizes play and enhances joint integrity. The flat design and 0.375" outer diameter effectively spread clamping force, reducing stress on connected materials and preventing deformation. This combination of corrosion resistance, dimensional accuracy, and robust material makes these washers a reliable choice for maintaining performance in industrial washers and fastener systems, ultimately lowering maintenance costs and improving safety.

Specification Summary & Compliance

This flat washer features an inner diameter (ID) of 0.134", outer diameter (OD) of 0.375", and thickness ranging from 0.057" to 0.067", designed specifically for use with 1/8" rivets in inch measurement systems. It is manufactured from zinc-plated steel, providing consistent performance without a rated hardness. The product complies with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead in steel alloys and is REACH (EC 1907/2006) compliant as of January 17, 2023, covering 233 Substance of Very High Concern (SVHC), ensuring adherence to environmental and safety regulations.
