10th November 2021

Bolts are used in every industry over multiple applications from holding storage vessels and structures to the ground to connecting high pressure pipework and holding wind turbine blades in place.

Application Notes

Paint on Various Substrates

9th November 2021

Most conventional coating thickness gages using eddy current or magnetic induction or other magnetic techniques can easily and accurately measure the thickness of paint on metals such as that on an automotive hood. They cannot measure paint on non-metal materials such as plastic bumpers, composites, wood or concrete.
