National Hardware Quick Links
The fixtures used were a set of clevis grips as seen in the picture. A ~5 lb pre-load was placed on the assembly prior to testing, but is automatically added to the test data. None of the threads on any of the samples were damaged and the barrels were easily unthreaded by hand. The points of failure were at the clevis pin as the sample was bent and flattened around them.
