<p>A method of indicating the tensile load on a fastener (2) including providing on said fastener an observation face (24) surrounded by a reference face (12), the planes of said faces being parallel to each other and adapted to move relative to each other as said tensile load changes. A reference face of a measurement instrument is placed against the fastener reference face (12) and the instrument determines the deviation of the observation face (24) from the plane of the instrument reference face. The deviation is compared with the known deviation characteristics for the type of fastener and the tensile load on the fastener (2) is indicated on the instrument.</p> |
