Abstract
A variably amplified load indicating fastener includes a fastener () detachably secured to a load indicator via a base member. The fastener () has an abutment which is moved by a change in length under an applied load. The load indicator includes a dial plate (), a needle () pivotally supported by the plate (), a compensating slot (), a driving slot, an elongated U-shaped element () disposed in the direction in which the load is applied when the fastener () is in use, and a first reference mark (). One side of the U is rigidly attached to the fastener. The closed end of the U is proximate to and movable by the abutment. The other side of the U extends through the compensating slot () and the driving slot (). The needle () is operatively coupled to the outer end of said second side. A sleeve with a second reference mark fits over the outer circumference of both the load indicator and the base member.
