Abstract
A device for captivating a variety of fasteners relative to a first member. A captivator includes a body adapted to be secured to the first member and a retainer received within the body and having a surface engaging a captured fastener. Together the body and retainer maintain the captivated fastener in place relative to the first member. Keyway surfaces can be provided upon the body or retainer or both and an external or internal key can engage the keyway surfaces to selectively lock the body and retainer together, such as during installation or replacement of the captured fastener. Upon removal of the key, the retainer is free to rotate and translate relative to the body. A two-part base includes a snap base and base retainer together secured on a panel. The snap base may include one or more grooves for engaging one or more protrusions on the base retainer. In some embodiments a fastener retainer is not required as the base retainer functions to secure the fastener to the assembly.
