An acousto-optic device may include an acousto-optic component carried by a chassis, and a fastener assembly for removably securing a cover to the chassis. The fastener assembly may include a base sleeve having an enlarged head, and a tubular body and extending through a cover passageway. The fastener assembly may include a retainer sleeve having a threaded interior secured to the threaded exterior of the base sleeve to define an anchor member, the anchor member having a threaded interior. The fastener assembly may further include a fastener, a shaft having a threaded exterior opposite the enlarged head and to be threaded through the threaded interior of the anchor member to capture the fastener to the cover and movable through the chassis passageway for removably securing the cover to the chassis.
