S-90481A242 0.188" ID x 1.25" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to the zinc-plated steel construction, extending the washer's lifespan in harsh industrial environments.
• Precise dimensional fit with a 0.188" inner diameter and 1.25" outer diameter, ensuring reliable performance and easy installation with No. 8 screws.
• Optimized load distribution due to the flat design and controlled thickness (0.036-0.065"), reducing surface pressure and preventing damage to assembled materials.
• Strict environmental compliance with RoHS 3 and REACH standards, making these washers suitable for global supply chains and eco-conscious industries.
• Versatile industrial application as a durable, general-purpose washer for machinery, equipment, and construction where consistent performance is critical.
• Cost-effective reliability from robust steel material, offering long-term value by minimizing replacements and maintenance needs.

Professional Applications & Engineering Value

These zinc-plated steel flat washers are engineered to address common challenges in industrial fastening, such as galvanic corrosion and uneven load distribution. The zinc plating provides a protective barrier against moisture and chemicals, significantly enhancing corrosion resistance in demanding settings like outdoor machinery, automotive assemblies, and electrical enclosures. With precise dimensions—including a 0.188" inner diameter tailored for No. 8 screws and a 1.25" outer diameter for broad surface coverage—these washers ensure secure fits and reduce the risk of loosening under vibration. This makes them ideal for industrial applications requiring dependable, long-lasting hardware that meets rigorous environmental standards without compromising on performance.
