Peak Testing Helped Fastener Distributor Save Customer $24,950


A customer of a fastener distributor was using liquid adhesive during the assembly process of gearboxes for solar panel tracking. The adhesive was allowing for variation in clamp load, slow production time, and messy application. The distributor was recommending a pre-applied adhesive patch to replace the liquid adhesive and needed validation testing to compare the two applications. The distributor had an engineering staff and testing capabilities, but the validation testing needed was not available in-house, so the distributor went to Peak innovations Engineering.


Peak innovations Engineering provided the validation testing the fastener distributor needed by using a torque-angle to failure test. The test results showed the pre-applied adhesive patch provided consistent joint performance, reduced assembly time, had excellent loosening resistance, better quality joint, and no mess.


Peak’s software allowed for detailed analysis with minimal time and effort. The fastener distributor would not have been able to do this testing without Peak. The Peak software and capabilities allowed the fastener distributor to develop a better understanding of the threshold point for the joints in the gearbox and ultimately providing its customer with a more confident recommendation.

Going from liquid adhesive to a pre-applied adhesive patch:

  • Eliminated application time
  • Eliminated application labor cost of $22,000
  • Eliminated mess
  • Reduced chance of warranty issues
  • Increased revenue
  • Improved consistency of the joint
  • Total cost savings to the customer: $24,950


  • Torque-angle to failure testing
