Clarendon Specialty Fasteners Welcomes Spring Solutions to the Group

We're delighted to announce that Spring Solutions has joined the Clarendon Specialty Fasteners group (part of Diploma PLC). The acquisition announced today (November 13th, 2025) marks an exciting milestone for Clarendon Specialty Fasteners as it continues to expand its capabilities and market reach.

Spring Solutions is an excellent fit for Clarendon Specialty Fasteners (“CSF”). Based in the UK, the business brings decades of expertise in serving the aerospace, defence, and industrial sectors. Spring Solutions specialises in delivering comprehensive value-added services spanning fasteners, adhesives, chemical management, tailored kitting, and complex supply chain solutions - capabilities that complement and enhance CSF's existing portfolio.

Spring Solutions' commitment to service excellence and innovation aligns seamlessly with CSF's core values and operational approach. The business will operate independently within the CSF group, allowing it to maintain the service standards and relationships that have made it a trusted partner for its customers.

Marc Hall, Managing Director of Spring Solutions, will lead the business as it joins the CSF group, reporting to Paul Sanders, Managing Director of CSF. Spring Solutions has an excellent team of dedicated employees whose expertise and commitment to customer success complements the CSF culture.

"Spring Solutions is an excellent strategic fit for CSF," said Paul Sanders, Managing Director of Clarendon Specialty Fasteners. "This acquisition strengthens our capabilities and market position in the UK Defence sector. Spring Solutions has built a strong reputation through its dedication to service excellence, and we are excited about the opportunities this partnership will create for growth and collaboration."

CSF is thrilled to welcome Spring Solutions into the group and looks forward to building on this foundation as both businesses continue to develop their global operations.
