This nut torque indicator cover includes a cover piece that is joined to an indicator piece. It is fastened to a nut/bolt assembly primarily by pressing it down onto and over the exposed threads of the bolt so that the indicator piece registers with the hex portion of the nut. A snap fit design is incorporated into the nut torque indicator cover such that the cover piece and indicator piece can rotate relative to each other. The cover piece fastens securely to the external threads of the bolt providing protection to the threads, while the indicator piece, secured by the hex flats of the nut, indicates the nut circumferential position, allowing an indication of any torque loss.

1. A position indicator assembly for use with a nut and a bolt which are or are to be threadedly engaged with each other, the assembly comprising: a cover piece having an open first end, a second end, and an open interior region with bolt engagement members such that the first end can be pressed down over the bolt and said bolt engagement members will engage said bolt so as to affix said cover piece thereto; andan indicator piece having a pointer for orientation in a preferred direction, which indicator piece is rotatably mounted to said cover piece adjacent said first end and has nut engagement members such that when said first end is pressed down over said bolt the indicator piece can engage said nut so as to be rotatable with said nut. 2. The position indicator assembly of claim 1, wherein said assembly has at least one of: bolt engagement members formed by tabs located on surfaces of said interior region of said cover piece, and nut engagement members formed by knurled surfaces of said indicator piece. 3. The position indicator assembly of claim 1, wherein when said cover piece is pressed down over the bolt such that the indicator piece has engaged said nut, said indicator piece can rotate with said nut relative to said bolt without rotation of the cover piece relative to said bolt. 4. The position indicator assembly of claim 1, wherein when said cover piece is pressed down over the bolt such that said bolt engagement members engages said bolt, said position indicator assembly is removable from said nut and bolt by unscrewing said cover piece from said bolt. 5. The position indicator assembly of claim 1, wherein interlocking clips positioned at an interface between the cover piece and the indicator piece form a slip fit juncture between said cover piece and said indicator piece. 6. The position indicator assembly of claim 5, wherein said slip fit juncture is formed by one of: snapping said cover piece and said indicator piece together, and joining said cover piece and indicator piece together via a partial thread. 7. The position indicator assembly of claim 6, wherein any snapping of said cover piece and said indicator piece together is facilitated by the presence of a relief slot in one of the cover piece and the indicator piece. 8. The position indicator assembly of claim 1, wherein said cover piece has an open second end. 9. A position indicator assembly for use with a nut and a bolt which are or are to be threadedly engaged with each other, the assembly comprising: a cover piece having an open first end, a second end, and an open interior region with bolt engagement members such that the first end can be pressed down over the bolt and said bolt engagement members will engage said bolt so as to affix said cover piece thereto;an indicator piece having a pointer for orientation in a preferred direction, which indicator piece is rotatably mounted to said cover piece adjacent said first end and has nut engagement members such that when said first end is pressed down over said bolt the indicator piece can engage said nut so as to be rotatable with said nut;wherein said assembly has at least one of: bolt engagement members formed by tabs located on surfaces of said interior region of said cover piece, and nut engagement members formed by knurled surfaces of said indicator piece; andwherein when said cover piece is pressed down over the bolt such that the indicator piece has engaged said nut, said indicator piece can rotate with said nut relative to said bolt without rotation of the cover piece relative to said bolt. 10. The position indicator assembly of claim 9, wherein when said cover piece is pressed down over the bolt such that said engagement member engages said bolt, said position indicator assembly is removable from said nut and bolt by unscrewing said cover piece from said bolt. 11. The position indicator assembly of claim 9, wherein interlocking clips positioned at an interface between the cover piece and the indicator piece form a slip fit juncture between said cover piece and said indicator piece. 12. The position indicator assembly of claim 11, wherein said slip fit juncture is formed by one of: snapping said cover piece and said indicator piece together, and joining said cover piece and indicator piece together via a partial thread. 13. The position indicator assembly of claim 12, wherein any snapping of said cover piece and said indicator piece together is facilitated by the presence of a relief slot in one of the cover piece and the indicator piece. 14. The position indicator assembly of claim 9, wherein said cover piece has an open second end. 15. A method for using a position indicator assembly with a nut and a bolt which are or are to be threadedly engaged with each other, the method comprising: providing a position indicator assembly having a cover piece and an indicator piece, with said cover piece having an open first end, a second end, and an open interior region with bolt engagement members such that the first end can be pressed down over the bolt and said bolt engagement members will engage said bolt so as to affix said cover piece thereto, and with said indicator piece having a pointer for orientation in a preferred direction, which indicator piece is rotatably mounted to said cover piece adjacent said first end and has nut engagement members such that when said first end is pressed down over said bolt the indicator piece can engage said nut so as to be rotatable with said nut;pressing the first end of said cover piece down over the bolt so as to be affixed thereto with said indicator piece engaging said nut; andwherein the pointer of said indicator piece is oriented in said preferred direction before engaging said indicator piece with said nut. 16. The method of claim 15, wherein said assembly has at least one of: bolt engagement members formed by tabs located on surfaces of said interior region of said cover piece, and nut engagement members formed by knurled surfaces of said indicator piece. 17. The method of claim 15, wherein when said cover piece is pressed down over the bolt such that the indicator piece has engaged said nut, said indicator piece can rotate with said nut relative to said bolt without rotation of the cover piece relative to said bolt; andwherein when said cover piece is pressed down over the bolt such that said engagement member engages said bolt, said position indicator assembly is removable from said nut and bolt by unscrewing said cover piece from said bolt. 18. The method of claim 15, wherein interlocking clips positioned at an interface between the cover piece and the indicator piece form a slip fit juncture between said cover piece and said indicator piece, and said slip fit juncture is formed by one of snapping said cover piece and said indicator piece together, and joining said cover piece and indicator piece together via a partial thread. 19. The method of claim 18, wherein any snapping of said cover piece and said indicator piece together is facilitated by the presence of a relief slot in one of the cover piece and the indicator piece. 20. The method of claim 15, wherein said cover piece has an open second end.
