Sorry, the mode is torque to failure using a fully electronic torque wrench and monitoring software tightening the bolts into a pre-constructed jig. this test is conducted in order to achieve the optimum tightening torque for a given fastener/jig. After pondering, I have forgot to test the...
pre-load is the key here, you really need a tensioning device to ensure correct preload/ torque has been applied, consider hydraulic tensioning systems, or if two expensive, consider Huck bolts or Rotobolt or variations on a theme of these two.

Hi,
I have an issue, while testing the break load of a fastener in Plated form, black self colour and greased forms, I experienced an unusal result in that the greased bolt actually produced a higher break load than the other two bolts. Can somebody explain the reasons why this may occur, for...
