Quality Certifications and Compliance

We are quality.

At CSS, quality isn’t just an external requirement — it’s part of our culture.

We embrace quality-by-design principles that are embedded in every process and every part we produce. As one of the first in our industry to achieve ISO certification in 1994, and among the pioneers in manufacturing and distributing precision parts internationally, CSS has always set the bar high. Today, we continue to uphold and exceed global standards, delivering a level of quality that goes beyond what customers typically expect from a supplier or partner.

The American Systems Registrar has audited and approved Connecticut Spring & Stamping for quality management systems applicable to the design, support and manufacture of springs, wire forms, metal stampings, and tooling and for the assembly of springs, stampings and purchased components.

We operate with disciplined quality management systems at every level.

Whether serving the medical, defense & firearms, aerospace, or government sectors, we follow strict industry-specific standards and procedures to ensure consistent, reliable results. Every tooling and component project is meticulously planned—from order processing and work instructions to production and final delivery—so our customers receive dependable products, every time.
