Fastener Testing and Qualification Services
Accredited Fastener Testing for Strength, Reliability, and Compliance
From aerospace bolts to oilfield connectors, the reliability of every assembly begins with the fasteners that hold it together. AADFW provides accredited fastener testing and metallurgical analysis to verify mechanical performance, coating integrity, and material composition. As a NADCAP-accredited and ISO/IEC 17025-certified laboratory, we deliver precision-driven results with faster turnaround times than larger testing networks — helping manufacturers, distributors, and OEMs maintain quality assurance and regulatory compliance across demanding industries.

Why Fastener Testing Matters
Fasteners play a critical role in safety, performance, and long-term durability across aerospace, oil & gas, and industrial manufacturing. Fastener testing ensures that each bolt, nut, and screw meets required strength, hardness, ductility, and coating standards — preventing failures in service.
AADFW helps engineers and quality teams:
- Confirm tensile strength, hardness, and elongation properties.
- Validate thread integrity, coating adhesion, and plating performance.
- Ensure compliance with ASTM F606, SAE, and MIL specifications.
- Support quality control, supplier validation, and root-cause failure analysis.
With precise data and certified results, AADFW gives fastener manufacturers the confidence to stand behind every component that leaves their production line.
Our Fastener Testing Expertise
Backed by decades of metallurgical and mechanical experience, AADFW supports fastener manufacturers, distributors, and end users with full-service testing programs. Our engineers and metallurgists understand the critical role fasteners play in load-bearing assemblies, high-temperature environments, and pressure applications.
We test fasteners of all sizes and materials — from aerospace-grade titanium and high-strength steel to plated carbon and specialty alloys — providing accurate, traceable results you can trust. Whether qualifying new suppliers, verifying heat treatment, or diagnosing a failure, AADFW delivers accredited results with speed and technical clarity.
