USA-Made Belleville Washers

Proposed tariffs and evolving regulations are imminent—ensure your supply chain stays ahead.

With USA-made Solon Belleville washers, you get unmatched quality, reliable lead times, and trusted local expertise—all while staying ahead of potential tariffs and evolving standards.

Here are 8 compelling ways why choosing Solon Belleville springs and washers are the smart choice for your business.

• Support American Manufacturing: Strengthen our economy by partnering with domestic manufacturers who deliver unmatched craftsmanship.
• Reliable Lead Times: Avoid delays and disruptions caused by shipping or customs issues, ensuring your projects stay on track.
• Material You Can Trust: Foreign-made Bellevilles use unknown raw materials. Faulty springs can lead to catastrophic failure- which led to the enactment of the Fastener Quality Act (FQA). The Congressional Subcommittee on Oversight and Investigations found adherence to standards to be intermittent, particularly with overseas suppliers. While Belleville washers are not specifically covered in the FQA, the justification for the act applies. The stresses in Belleville washers can be substantially higher than those components covered by FQA. This makes it even more critical to use Bellevilles manufactured in the USA, using domestic steels.
• Solon Quality: We set the standard for workmanship and precision, delivering consistent performance you can count on. Solon's standard Belleville springs and washers conform with ISO 19690-2 standard tolerances. 
• Stay Ahead of Future Changes: Regulations and tariffs are on the horizon. Buying American ensures compliance with evolving standards and secures your supply chain.
• Local Expertise: Our support and engineering teams are ready to assist with application optimization—no delays, no overseas time zones.
• Sustainable Practices: Choosing USA-made Belleville washers reduces your carbon footprint through shorter supply chains, minimized transportation emissions, stricter energy standards, and eco-friendly manufacturing practices, making it a smarter and more sustainable choice.
• Support the Build America, Buy America Act: Align with federal standards while contributing to national growth. Learn more about BABA.
