WebNo. The bolt has not failed due to pretension. We recently received a similar question. The pretension does not reduce the available tensile strength of the bolt. People often feel that a bolt pretensioned to 70% of its tensile strength has already violated the tension limit state for the bolt and any additional applied tension cannot be allowed. WebIn the process of Skidmore Bolt Testing, also referred to as Pre-installation Verification Tension Testing and Rotational Capacity Testing, a bolt, nut, and washer assembly are inserted into the tension reading equipment.
