QUARTER TURN FASTENER

摘要

A quarter turn fastener includes a deflectable head and part in assembly legs for securing the fastener in a subassembly with one component positioned between the deflectable head and the part in assembly legs. Cooperating lock arms on the fastener and lock ribs on the component secure the fastener against unintended rotation for loosening. Stop ribs on the component limit the distance the fastener can be rotated. Main body legs are provided for securing a second component with the subassembly. Cooperating structures of the fastener and the components limit the fastener to rotate only in the lock direction from the unlocked position and in the unlock direction from the locked position.
