Bolt and nut evaluator

Abstract

A device for testing fasteners such as nuts and bolts is described which is comprised of a fixed base plate having a number of threaded and unthreaded holes of varying size for receiving the fasteners to be tested, a torque marking paper taped on top the fixed base plate for marking torque-angle indicia, a torque wrench for applying torque to the fasteners being tested, and an indicator for showing the torque applied to the fastener. These elements provide a low-cost, non-destructive device for verifying the strength of bolts and nuts.
