Claim 4

A fastener comprising nut means for attachment to a first workpiece, and stud means for attachment to a second workpiece for mating with said nut means for holding said first and second workpieces together, said stud means including a housing having a tubular portion, an open end, an end opposite said open end, and a base at said open end, means engaging said base for holding said housing to a workpiece with freedom for limited lateral floating movement while precluding substantial rotation of said housing relative to such a workpiece, a stud having a head at one end and a threaded shank projecting from said head, said stud being received in said housing with said shank extending toward said open end thereof, said housing and said stud having interengaged means for holding said stud in said housing, a washer around said shank, said washer having two radially outwardly extending tabs diametrically opposite from each other, said tubular portion of said housing having two slots therein diametrically opposite from each other and intermediate the ends thereof receiving said tabs for thereby permitting said washer limited axial movement relative to said housing and preventing substantial rotation of said washer relative to said housing, said washer having teeth thereon facing said open end of said housing, a compression spring biasing said washer outwardly toward said open end, said nut means having teeth on the outer end thereof for engagement with said teeth of said washer for providing a resistance to said rotational movement between said nut means and said washer, and a cover member, said cover member including an end wall and a tubular wall, said end wall being positioned over said opposite end of said housing and said tubular wall receiving said tubular portion of said housing, said tubular wall of said cover member having an inwardly deflected dimple received in one of said slots in said tubular portion of said housing for thereby holding said cover member to said housing.

Claim 5

A fastener comprising nut means for attachment to a first workpiece, and stud means for attachment to a second workpiece for mating with said nut means for holding said first and second workpieces together, said stud means including a housing having a tubular portion, an open end, an end opposite said open end, and a flat base at said open end, said base including two radially outwardly extending tabs, a basket member attachable to a workpiece and having opposite upstanding flanges having slots therein receiving said tabs, said flanges being spaced farther apart than the width of said housing and said slots being larger than said tabs whereby said housing is permitted limited floating movement while being precluded from substantial rotation relative to said basket member, said flanges being of resilient material so as to be deflectable and permit removal and replacement of said housing, said opposite end of said housing having axially extending notches therein having flat inner edges falling in a radial plane, said head of said stud having a circular periphery complementarily engaging the inner surface of said tubular portion of said housing, and having a plurality of lugs extending outwardly from said circular periphery, said lugs being received in said notches and engaging said inner edges thereof, said outer end intermediate said notches being bent over said head, for thereby holding said stud in said housing, and a cover member, said cover member including an end wall and a tubular wall, said end wall being positioned over said opposite end of said housing and said tubular wall complementarily receiving said tubular portion of said housing, said housing and said cover member having interengaged means for holding said cover member to said housing, a stud having a head at one end and a threaded shank projecting from said head, said stud being received in said housing with said shank extending toward said open end thereof, said housing and said stud having interengaged means for holding said stud in said housing, a washer around said shank, said washer having teeth thereon facing said open end of said housing, said washer having a plurality of radially outwardly extending tabs, said tubular portion of said housing having slots therein intermediate the ends thereof receiving said tabs for thereby permitting said washer limited axial movement relative to said housing and preventing substantial rotation of said washer relative to said housing, and a compression spring biasing said washer outwardly toward said open end, said nut means having teeth on the outer end thereof for engagement with said teeth of said washer for providing a resistance to said rotational movement between said nut means and said washer.

Claim 6

A fastener comprising nut means for attachment to a first workpiece, and stud means for attachment to a second workpiece for mating with said nut means for holding said first and second workpieces together, said stud means including a housing having a tubular portion, an open end, an end opposite said open end, and a flat base at said open end, said base including two radially outwardly extending tabs, a basket member attachable to a workpiece and having opposite upstanding flanges having slots therein receiving said tabs, said flanges being spaced farther apart than the width of said housing and said slots being larger than said tabs whereby said housing is permitted limited floating movement while being precluded from substantial rotation relative to said basket member, said flanges being of resilient material so as to be deflectable and permit removal and replacement of said housing, said opposite end of said housing having axially extending notches therein having flat inner edges falling in a radial plane, said head of said stud having a circular periphery complementarily engaging the inner surface of said tubular portion of said housing, and having a plurality of lugs extending outwardly from said circular periphery, said lugs being received in said notches and engaging said inner edges thereof, said outer end intermediate said notches being bent over said head, for thereby holding said stud in said housing, and a cover member, said cover member including an end wall and a tubular wall, said end wall being positioned over said opposite end of said housing and said tubular wall complementarily receiving said tubular portion of said housing, said housing and said cover member having interengaged means for holding said cover member to said housing, a stud having a head at one end and a threaded shank projecting from said head, said stud being received in said housing with said shank extending toward said open end thereof, said housing and said stud having interengaged means for holding said stud in said housing, a washer around said shank, said washer having teeth thereon facing said open end of said housing, said washer having a plurality of radially outwardly extending tabs, said tubular portion of said housing having slots therein intermediate the ends thereof receiving said tabs for thereby permitting said washer limited axial movement relative to said housing and preventing substantial rotation of said washer relative to said housing, and a compression spring biasing said washer outwardly toward said open end, said nut means having teeth on the outer end thereof for engagement with said teeth of said washer for providing a resistance to said rotational movement between said nut means and said washer.
