Overview Specification
Quality is at the core of everything we do. Each collar bolt undergoes rigorous inspection and quality control throughout the manufacturing process, ensuring consistent performance and full compliance with industry standards. We manufacture to recognised specifications such as DIN, ASTM, and BS, and can also work to bespoke drawings and technical requirements.
Collar bolts, also known as fitted bolts, are often used where precise alignment and load-bearing performance are essential. From turbine assemblies to structural connections, Canmec’s custom components deliver secure fastening in applications where failure is not an option.
With flexible lead times and a responsive, knowledgeable team, we support everything from one-off prototypes to high-volume production. Our additional services, including heat treatment, protective coatings, and specialist finishes, ensure every bolt is ready for the conditions it will face.
