Abstract

A trapezoidal thread form includes a thread having a trapezoidal cross sectional shape the thread including an apex surface (42) two side surfaces (32,34) and a valley; and a thread wear indicator (50) formed in one of the apex surface (42) and one of the side surfaces (32,34). The thread wear indicator (50) may include a v shaped channel (52) formed in one of the apex surface (42) and one of the side surfaces (32,34) or the thread wear indicator (50) may include a series of material layers each layer having a physical characteristic that is different from an adjacent material layer. The thread wear indicator (50) indicates excessive or unsafe thread wear when the v shaped channel (52) is indistinguishable from the apex surface (42) or the side surface (32,34) or when a first layer wears sufficiently to show a second layer.
