ABSTRACT:
A load indicating fastener comprising a load indicator and a fastener body. The load indicator comprises an annular body defining a through hole having a minimum diameter and a plurality of protuberances integral with a first face of the annular body and a corresponding plurality of indentations in a second face of the annular body opposite from the first face. The fastener body comprises a series of threads, a head defining a contact surface, and a shank depending from the contact surface. The shank includes a first portion having a first outside diameter less than the through hole minimum diameter such that the load indicator is received on the shank first portion and a second portion including at least one radially extending member having a second outside diameter greater than the through hole minimum diameter such that the load indicator is retained on the fastener body thereby.
