Abstract
A tensile member such as a bolt fastener comprises an elongated body formed with an open-ended longitudinal bore extending through an intermediate region of the body. A tubular sleeve and a test rod extend coaxially into the bore and are secured therein at longitudinally spaced positions within the intermediate region. The tubular sleeve and the test rod each have a free end adjacent to the open end of the bore. Tensile stress within the intermediate region of the body of the tensile member is measured by measuring relative longitudinal displacement between the end faces of the sleeve and test rod at their free ends.
