摘要：
A method and a gauge for inspecting a self-locking threading provided close to one end of a tubular component used for exploration or operation of hydrocarbon wells, the threading including a lead with a constant width and thread root widths that increase in the direction of a distal surface of the tubular component. The gauge can be displaced in the self-locking threading to a locking position, the locking position then being marked and compared with a reference locking position.
