Catch Problems Before They Cost You

Whether you order testing for raw materials, finished fasteners, or to research quality issues with production, you will benefit from identifying and correcting weaknesses or defects before costly problems occur. Laboratory Testing Inc. offers a broad range of fastener testing and inspection capabilities to keep your business operating efficiently:

Fastener Testing

Nondestructive Testing

Magnetic Particle Inspection and Liquid Penetrant Testing are available to identify surface-breaking discontinuities without damaging your test samples. X-ray Inspection is also offered for more thorough testing.

Dimensional Inspection

Dimensional inspection of fasteners with internal or external threads is performed by the inspectors in our division called LTI Metrology using CMM, Smartscope and optical inspection methods. The Smartscope is programmable for repeat measurement, ensuring accurate and efficient inspection of large-quantity orders. Dimensional inspection is performed in accordance with NAS, MS and ANSI specifications.

Chemical Analysis

A variety of chemistry services are provided for analyzing elements and impurities, revealing material composition and identifying materials including Spectrometry, ICP-AES, ICP-MS, AES, FTIR, Carbon/Sulfur/Nitrogen/Oxygen/Hydrogen Determination and Positive Material Identification (PMI).

Metallurgical Testing

A wide-range of microstructure and macrostructure examinations are performed including grain size, decarburization / carburization, plating thickness, surface contamination, thread examination, macro-etch (ASTM E340) and more. Microhardness testing and failure analyses are also performed by our materials engineers.

Mechanical Testing

LTI can determine the mechanical properties of your materials such as strength, hardness and load capacity. Equipment is available to test fasteners of all sizes including tensile machines with capacities from 100 to 400,000 lbs. Hardness testing, axial tension fatigue and yield strength testing are also offered..

Failure Analysis

Our materials engineers complete thorough failure investigations to determine the root cause of failed fasteners. All work and results are documented for you in a Failure Analysis Report.

Laboratory Testing Inc. is more than a materials and fastener testing company. We also provide related services to save you time and simplify your job. Let us prepare any specimens needed for testing or take advantage of the calibration services offered by LTI Metrology to certify the measurement accuracy of your measuring tools, gages, torque wrenches, masters, CMMs, surface plates and many other measuring instruments.
