Fastener Testing

Avoid Costly Problems & Failures

Fastener testing can help ensure the reliability of fasteners used in critical applications. Laboratory Testing Inc. provides all the fastener services required to support our clients in making important business decisions and resolving problems.

Testing for Manufacturers to End Users

Dimensional inspectionIf you are selecting a fastener or material for fastener production, we can help you compare material composition and mechanical properties to be sure you are buying a reliable product. Our chemical analysis and mechanical testing services can also verify that fasteners you routinely purchase or manufacture continue to meet your requirements.

LTI also offers non-destructive solutions for production questions. Dimensional inspection services can verify measurement accuracy of all fastener features, including threads. A variety of NDE inspection methods can identify surface or sub-surface discontinuities and defects.

We have the engineers and research capabilities to evaluate in-service issues or perform a complete root cause failure analysis.
