Our History
A Legacy of Craftsmanship, Innovation, and Precision—Now United as New England Spring
New England Spring was formed in 2023 through the merger of two respected manufacturers: Colonial Spring of Bristol, CT and Hardware Products of Chelsea, MA. This strategic consolidation brought together more than 75 years of spring manufacturing expertise, combining legacy craftsmanship with modern production capabilities in a single, state-of-the-art facility in Bristol. With enhanced efficiency, expanded capacity, and industry-leading certifications including ISO 9001:2015 and AS9100D, New England Spring now serves a diverse range of aerospace, defense, medical, industrial, and automotive customers with greater speed and precision than ever before.
A Tradition of Growth and Innovation
Colonial Spring
From a 1946 Hartford startup to a trusted precision manufacturer serving advanced industries.
Founded in 1946 in Hartford, Connecticut, Colonial Spring built its reputation on craftsmanship and continuous improvement, relocating to Bristol in 1977 to support expansion. Over the decades, the company marked several major milestones:
1999: Acquisition of HanDee Spring Co., expanding into the aerospace sector
2003–2004: Achieved ISO 9001 and AS9100 certifications
2004: Merged with Triple A Spring, strengthening wire and strip forming capabilities
2006: Became wholly owned by SEI MetalTek, fueling continued investment and modernization
Through steady growth, Colonial Spring became a trusted partner for manufacturers requiring precision springs, wire forms, and strip components.
One of America’s Oldest Spring Manufacturers
Hardware Products
A 150-year legacy of reliability, engineering excellence, and evolving spring production capabilities.
Hardware Products began in 1866 in Boston, Massachusetts, initially producing machined hardware before shifting into spring manufacturing as demand grew. Its legacy includes:
1971: Acquired by George Underwood, ushering in new expansion
1991–1993: Purchased by Catalyst Group and later SEI MetalTek, strengthening its industrial reach
Early 1990s: Relocation to Chelsea, MA to modernize operations
With more than a century of history, Hardware Products became known for reliability, engineering knowledge, and diverse spring manufacturing capabilities.
A Stronger Future, Built Together
New England Spring
Two historic companies merged to create a modern, unified leader in precision spring manufacturing.
The 2023 merger of Colonial Spring and Hardware Products officially formed New England Spring, aligning two longstanding companies under one unified vision. Today, New England Spring delivers advanced forming, coiling, stamping, and secondary processing capabilities backed by robust quality systems and an employee-driven culture.
