ABSTRACT:
A quick-release fastener comprises a threaded stud (11) and a complementarily threaded receptacle (1), the stud and receptacle each having one or more longitudinally extending threaded and unthreaded portions (15,8). The or each threaded portion (15,8) of the stud (11) and receptacle (1) respectively has a lesser angular width than the unthreaded portions of the receptacle and stud respectively. The fastener has at least one stop (9) at one edge of the or one of the threaded portions (8,15) on the stud or receptacle, whereby the stud can be inserted into the receptacle with the threaded (8,15) and unthreaded portions of the stud (11) and receptacle (1) respectively aligned and can thereafter be rotated to engage the respective threaded portions. The stop (9) prevents over-rotation of the stud (11) within the receptacle (1) thereby to define a fastened orientation of the stud within the receptacle.
