For many years, Auhan has routinely and extensively tested critical mechanical properties of our high tensile stock in our own in-house laboratory. Auhan has invested in state-of-the-art equipment, including

• Instron Satec 600DX Universal Testing Machine - (Click for image)
  Allowing Proof Load Testing and Ultimate Tensile Strength determination on bolts and proof load testing of nuts.
  
  
• Future Tech FV700 Vickers Hardness Tester - (Click for image)
  To allow accurate point determination of fastener hardness.
  
  
• Kodak Profile Projector - (Click for image)
  For assessment of fastener dimensional characteristics.
  
  
• ATM Abrasive Cut-Off Machine and ATM Hot Mount Press - (Click for image)
  For accurate preparation and mounting of cross-sectional samples for microscopic analysis.

In addition to these state-of-the-art pieces of equipment we have literally hundreds of thread gauges, straightness gauges, vernier calipers and thread micrometers to ensure every dimension is within specified tolerances.
