Pin attached to bottom of hole through long axis of machine bolt can be used to indicate correct bolt tension without torque meters or extensometers. Bolt elongates when tightened, but pin does not, and so appears to recede within bolt head. Steps cut in exposed end of pin would indicate acceptable range of tightness. Design would be particularly convenient in field locations without specialized instrumentation.
