Terminal Cup Washers
Terminal cup washers are critical for creating a secure and reliable connection. By preventing wire slippage under a screw head, they keep your assemblies intact. This precise functionality is essential in high-performance and mission-critical environments. For nearly 100 years, our components proudly made in the USA have secured these vital connections.

The Engineer's Choice for Reliable Connections
Your complex designs require hardware built for precision. We engineer our components to meet tight tolerances and the strict demands of commercial and defense applications.

Fail-Safe Performance for Critical Applications
Precision engineering leaves no room for error. Seastrom produces washers that are precision-engineered to ensure your mission's success. Our quality management is certified to rigorous standards to safeguard your projects against component failure and costly regulatory risks. This commitment to quality eliminates the vulnerabilities of standard hardware.

Brass and Stainless Steel Options
We understand that the right material is just as important as the design. Brass terminal cup washers offer superior electrical conductivity, while stainless steel terminal cup washers provide maximum durability and corrosion resistance in harsh environments.
