The function of this particular collar member is primarily for the same purpose asv those in the herein previously described struc tures, but, in addition,.affords. a protective cover- » whateverrposition it is placed on the boltV or the 16 ing at the outer end ofthe nut.

As to the provision of said- slots 48 it so In this l two-piece collar structure the lower annular edge ' portion of the outer piece 53 just touches the top ‘ of the annular marginal bead yor shoulder 4I of the base or main body portion of the nut. A further structural modification is illustrated in Fig. 19. This structure, in general, is quite similar to those previously described, and also is here noted that the same can be cut in the 55 except as to the manner in which thek flanged neckl portion 36 either before the compressing collar member 31 is attached to the'body por- ' and Vcontracting of this part, but preferably after` tion proper of the nut.

The resilient confin ing collar or ring member, however, is in a mod iiiedjform, in thatY it is cupped in an integral formation providing a crowned portion49 which covers and encloses the upper open end of the the nut body substantially as in the previouslyde scribed structures, but the lower edge portion of the collar member 31 is welded, as at 51, to the annular top face of the base portion of the nut body proper. ` ,y While the herein described multiple-piece struc tures may be the more desirable and practical'in the manufacture of the nut of the present inven nut body proper and is spaced a sufficient Vdis tion because of certain advantages in the'proce tance therefrom to afford ample clearance for 70 dure incidental thereto, the nut can be made in the protruding end of the bolt .or like element an integral one-piece structure and is As_o con to .which the nut is applied, as, :for example, in an instance vapproximately like> that illustrated in_Fig.`_.l,¿where the applied nut is adjacent the endpfzthegbolt. ~ ’ . .
