Fasteners
Special screws for custom goals: the full range from PSM CELADA Fasteners
In the landscape of industrial fastening solutions, our range of special screws stands out as a technical and reliable answer to the most specific needs of designers and purchasing managers. The offering includes self-tapping screws, self-forming screws, and customer-drawn components, selected and tested to ensure dimensional accuracy, supply repeatability, and consistent mechanical performance even under severe operating conditions.
Self-tapping and self-forming screws, TIEMME series
The TIEMME series, dedicated to self-tapping and self-forming screws, is designed for direct fastening into plastics, composite materials, and light alloys, environments where high holding power and specific pull-out resistance are required. Optimized point and thread geometries allow efficient insertion with reduced stress generation in the material, preserving the assembled component’s aesthetic and structural quality. These screws are intended for high-productivity assembly processes and for applications that demand repeatable tolerances and long-term performance.
Custom fasteners and bolts, in partnership with BULTEN
For projects that require non-standard solutions, we supply custom fasteners and bolts manufactured to customer drawings through our collaboration with BULTEN. This product line expands design possibilities by offering multiple head shapes, body profiles, thread pitches, and point types, including the availability of metric threads. The tailored approach includes technical consultancy for selecting the best materials and geometries according to the expected loads, supporting customization even for industrial volumes.
Surface treatments and functional features
All series can be supplied with a comprehensive range of surface treatments designed for corrosion protection, friction-coefficient stabilization, and sealing. The finishes and coatings offered follow standards used in the Automotive and Industrial sectors, ensuring environmental compatibility and performance throughout the product’s life cycle. The availability of specific treatments makes it possible to balance chemical-physical resistance, initial lubrication, and aesthetic requirements, delivering solutions suited to diverse operating conditions.
Technical support
We combine quality control, technical expertise, and a network of partners to ensure that supplies meet required specifications. Inspection of mechanical, dimensional characteristics, and of surface treatments is an integral part of the process, as is technical consultancy for design integration and assembly optimization.
We put our experience at the service of your projects, offering special fastening solutions designed and produced to meet the most complex industrial challenges. Visit our online stand at Expometals or contact us via email to choose the fastening solution best suited to your needs.
