A locknut including a body having a stud receiving inner surface and an outer surface having a ridge with a shoulder and a cylindrical portion next to the shoulder, an O-ring mounted on the cylindrical portion, a shroud having a cylindrical portion which overlies the cylindrical portion of the nut and engages the O-ring on the cylindrical portion of the nut and conceals it when a shoulder on the cylindrical portion of the shroud is in engagement with the shoulder on the ridge of the nut. The cylindrical portion of the nut has an axial length which is greater than the cylindrical portion of the shroud so that the end of the nut protrudes beyond the end of the shroud when the above-mentioned shoulders are in engagement. A bolt having a head containing structure such as described above relative to the locknut.

A locknut comprising an annular locknut body having an inner surface and an outer surface, first and second ends on said locknut body, means on said inner surface for engaging a stud in mounted relationship, a first ridge extending outwardly from said outer surface of said locknut body between said first and second ends, a first shoulder on said first ridge, an outer cylindrical portion on said outer surface of said locknut body between said first end and said first shoulder on said first ridge, a groove in said outer cylindrical portion, an O-ring in said groove, an annular shroud having an inner surface and an outer surface, first and second ends on said annular shroud, a second ridge on said annular shroud extending inwardly from said inner surface of said shroud proximate said first end of said shroud, a second shoulder on said second ridge for engaging said first shoulder, an axially extending inner portion on said second ridge, said inner cylindrical portion being of larger diameter than said outer cylindrical portion of said locknut body for rotatably receiving said outer cylindrical portion when said first and second shoulders are in engagement, said locknut body having a first axial length between said first end thereof and said first shoulder, said shroud having a second axial length which is less than said first axial length between said second shoulder and said first end of said shroud to thereby permit said first end of said locknut to protrude beyond said first end of said shroud when said first and second shoulders are in engagement, a key-receiving configuration on said second end of said locknut body, said second end of said shroud extending beyond said second end of said locknut body, said O-ring having an outer diameter which is larger than said inner diameter of said inner cylindrical portion of said second ridge to thereby engage said inner cylindrical portion to provide an interference fit therebetween to retain said locknut body and said shroud in assembled relationship when said locknut body is not mounted on said lug and to permit said shroud to be physically rotated relative to said locknut body when said locknut body is mounted on said stud while preventing rotational movement of said shroud relative to said locknut body due to vibration, said groove being located within the axial extent of said inner cylindrical portion thereby being wholly concealed within said shroud when said first and second shoulders are in engagement.
