"[..] and in such a way that there will be no tendency of the driver to cam out of the recess when united in operative engagement with each other."[1] Wikipedia says: "The design is often criticized for its tendency to cam out at lower torque levels than other "cross head" designs. There has long been a popular belief that this was a deliberate feature of the design, to assemble aluminium aircraft without overtightening the fasteners.[14]: 85 [15] Extensive evidence is lacking for this specific narrative, and the feature is not mentioned in the original patents.[16] However, a 1949 refinement to the original design described in US Patent #2,474,994[17][18][19] describes this feature.
