Fasteners Intelligence System
In safety-critical industries, failures rarely originate from the fastener alone.
They arise from unvalidated assumptions.
Preload, friction, stiffness, fatigue behaviour, and joint compliance are often assumed — not validated — during fastener selection.
Meeting a manufacturing standard does not guarantee joint integrity under real service conditions.
Most failures occur due to system-level gaps — not material defects alone.
With FIS, design becomes compliance.
Without validation, design is intent.
FIS exists to eliminate assumption-driven risk by enforcing engineering responsibility for bolted joint validation — before failure can occur in service.
Fasteners Intelligence System
Most fastener suppliers comply with a single standard.
FIS
integrates many — into one validated engineering
outcome.
FIS maps and translates multiple global standards into a single, unified engineering validation framework.
Eliminates conflicting assumptions between standards, calculation tools, manufacturing processes, and inspection methods.
Prevents late-stage compliance failures, redesign loops, and costly program delays before they occur .
Methodology-driven and tool-independent — ensuring robustness beyond any single software platform or calculation approach.
It aligns, cross-references, and connects them into one validated engineering framework.
Core bolted joint calculation and validation, including preload determination, joint stiffness, fatigue safety, and failure mode analysis.
Aerospace-grade bolted joint integrity requirements addressing margin of safety, verification rigor, and mission-critical reliability.
Flanged joint assembly, pressure boundary integrity, gasket behavior, and bolting practices for high-risk systems.
International alignment for fatigue behavior, preload consistency, thread geometry, tolerances, and material compliance.
Regional and program-specific aerospace requirements integrated into FIS to ensure global OEM acceptance and audit readiness.
Comparative Outcome
Engineering-driven design basis
Calculated and verified validation
Multi-standard alignment (VDI, NASA, ASME, ISO, EN)
Early risk identification and mitigation
Built-in audit readiness
High OEM confidence
Catalogue-driven selection
Assumed validation
Single-standard focus
Late risk discovery
Reactive audits
Conditional OEM confidence
Clarifying Scope
Not catalogue-based fastener selection
Not a single-standard checklist
Not a post-failure justification exercise
FIS is proactive engineering intelligence — designed to prevent failure, not explain it after the fact.
Intended Audience
FIS is engineered for programs where joint integrity is mission-critical and validation cannot be assumed.
Programs requiring rigorous joint validation, margin accountability, and audit-ready engineering documentation.
Suppliers accountable for subsystem integrity, compliance flow-down, and multi-standard alignment.
High-load, fatigue-sensitive, vibration-prone, or failure-intolerant bolted joint environments.
Programs demanding traceable engineering evidence across the full product and service lifecycle.
If your program cannot tolerate
assumptions
,
undocumented decisions, or late-stage compliance risk —
FIS
was built for you.
Engineering Outputs
FIS produces engineering evidence , not assumptions — delivered in formats aligned with OEM, regulatory, and program requirements.
Complete bolted joint analysis including preload determination, stiffness evaluation, fatigue safety, and failure mode verification.
Clear, auditable safety margin documentation aligned with aerospace, defence, and high-reliability program expectations.
Structured mapping between VDI, NASA, ASME, ISO, EN, and program-specific standards to eliminate compliance gaps.
Traceable linkage between validated engineering assumptions, production processes, inspection plans, and acceptance criteria.
End-to-end batch, lot, material, and process traceability records retained in accordance with customer, regulatory, and full program lifecycle requirements.
Every FIS deliverable is designed to withstand technical scrutiny, audits, and real-world service conditions.
From melting to plating.
From intent to assurance.
From components to confidence.
