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, dimensional inspection and failure analysis capabilities to keep your business operating efficiently:

Fastener Testing

Metallurgical Testing

A wide-range of microstructure and macrostructure examinations is performed including:Material testing digital imaging

  • Grain Size
  • Carburization / Dearburization
  • Plating Thickness
  • Surface Contamination
  • Alpha Case
  • Thread Examination
  • Microstructure
  • Macro-etch
  • Grain Flow
  • Microhardness

Root Cause Failure Analysis is also offered.

Mechanical Testing

LTI can determine the mechanical properties of your materials such as strength, hardness and load capacity.

  • Hardness Testing
  • Magnetic Permeability
  • Double Shear
  • Yield Strength
  • Wedge & Axial Tensile
  • Proof Load Testing
  • Tension Fatigue Test
  • Cone Strip Test
  • Flattening
  • Creep Testing
  • Stress Rupture Test
  • Hydrogen Embrittlement  / Stress Durability

Equipment is available to test fasteners of all sizes including tensile machines with capacities from 100 to 600,000 lbs.

Chemical Analysis

A variety of chemistry services are provided for analyzing elements and impurities, revealing material composition and identifying materials.

  • ICP Spectrometry (ICP-AES, ICP-MS)
  • AES Analysis
  • FTIR Analysis
  • Carbon / Sulfur / Nitrogen / Oxygen / Hydrogen Determination
  • Positive Material Identification (PMI)

Salt Spray Testing

Nondestructive Testing

We will identify surface-breaking discontinuities without damaging your test samples.

  • Magnetic Particle Inspection
  • Liquid Penetrant Testing
  • Ultrasonic Testing
  • X-ray Inspection (Radiography)

Dimensional Inspection

Dimensional inspection is performed in accordance with NAS, MS and ANSI specifications on fasteners with:

  • Internal threads
  • External threads

Inspectors in our division called LTI Metrology use CMM, Smartscope and optical inspection methods. The Smartscope is programmable for repeat measurement, ensuring accurate and efficient inspection of large-quantity orders.

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.

Additional Services

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.
