ABSTRACT:
An industrial quarter-turn fastener assembly comprises a sheet metal turn member having a turn head, a shank portion and a nose portion; a cap member through which the shank portion extends; and a helical coil spring. In one embodiment the fastener assembly is a blind fastener which is tilted to pass through a hole in a first panel which hole is smaller than the width of the nose portion and in another embodiment the shank portion is held to the first panel by a locking ring. To secure a second panel to the first panel, the nose portion is pushed through a slot hole in the second panel and the fastener turn head is rotated a quarter turn.
