Abstract
A retainer includes a cylindrical sleeve projecting downwardly into a hole in a plate with a flange at the lower end of the sleeve engaging the underside of the plate. Resilient fingers struck out from the sleeve engage the top of the plate to cooperate with the flange in holding the sleeve in place. A fastener initially is threaded along dimples in the sleeve to hold the fastener while permitting the latter to be threaded down into a member beneath the plate. As the fastener is threaded down, its head engages the sleeve which is crushed between the head and the plate so as to be out of the way.
