Custom engineered fasteners require more than production — they demand technical validation, material selection, process control and supply chain reliability.
We support OEMs and industrial companies in the development and supply of components manufactured according to technical drawings and specific application requirements.
Unlike standard components, a structured approach is required, involving engineering validation, production process definition and strict quality control.
We act as a technical sourcing partner, managing the entire process from feasibility to serial supply.
Custom fastener projects require more than production — they demand technical validation, process control and supply chain reliability.
We manage custom engineered fasteners through a structured and engineering-driven process, from feasibility to serial production.
• Technical drawing analysis and feasibility review
• Material selection (carbon steel, alloy steel, stainless steel, special materials)
• Process definition (cold forging, machining, secondary operations)
• Surface treatments and coatings (zinc plating, zinc flake, HDG, PTFE, others)
• Supplier selection and qualification
• Sample production and validation
• PPAP Level 3 (on request)
• Serial production and supply management
Custom engineered fasteners projects often fail due to technical and supply chain issues that are underestimated in early stages.
• Incorrect tolerances causing assembly misalignment or failure
• Coating failures leading to premature corrosion or rejection
• Hydrogen embrittlement risk in high-strength fasteners after plating
We approach custom fastener projects with a focus on risk prevention, ensuring technical validation and supply control at every stage.
• Early-stage drawing and feasibility validation
• Material and coating verification before production
• Selection of qualified and monitored suppliers
• Pre-production samples and functional testing
• Control of critical processes (heat treatment, coating, tolerances)
• Continuous quality monitoring during serial production
• Structured supply planning to ensure consistency
Examples of custom fasteners developed for different industrial applications and technical requirements.
Special component with secondary machining operations and controlled mechanical properties.
Stud bolts and special fasteners manufactured according to ASTM requirements, with full material traceability and certification (EN 10204 3.1).
Material selection is a critical phase in custom fastener development, directly affecting mechanical performance, corrosion resistance and long-term reliability.
Each material is defined based on application requirements, operating environment and certification needs.
Depending on project requirements, we ensure full control over materials, processes and documentation across the entire supply chain.
• EN 10204 3.1 material certificates
• Dimensional and mechanical test reports
• Coating certifications and compliance
• PPAP documentation (Level 3)
• Batch traceability and production records
• Supplier qualification and monitoring
