摘要

#CMT# #/CMT# The nut (10) has a base body (12) comprising a screwing aperture (14) with an internal thread (16) and a collar (18) radially projecting from the base body. An opposite side of the collar comprises a protruding bar (26), where the opposite side of the collar faces away from the base body. The collar comprises a helical trimming (22) spirally provided on the base body. The base body comprises an axial recess rotating around the screwing aperture along the side of the collar. The nut is made from plastic. #CMT#USE : #/CMT# Collar nut for fastening attachments at a threaded bolt of a body of a motor vehicle i.e. passenger car. #CMT#ADVANTAGE : #/CMT# The opposite side of the collar comprises the protruding bar, where the opposite side of the collar faces away from the base body, so that the attachment nut is pressed to the car body by springy movement provided by the helical trimming, thus improving flexibility and operative connection between the attachment and a mounting part and reliably securing the attachment to the car body with desired biasing force regardless of the torque to screw on the nut, and hence ensuring safe fixture. The collar is made of plastic, so that the damages to the attachments are reliably prevented. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top perspective view of a collar nut. 10 : Collar nut 12 : Base body 14 : Screwing aperture 16 : Internal thread 18 : Collar 22 : Helical trimming 26 : Protruding bar.
