Abstract
A bolt and receiver are provided to securely attach a device (e.g. light reflector or a lane marker) to a surface (such as a roadway). In addition to initially attaching the device to the surface, the bolt will nest progressively within the receiver as the surface thickness erodes or deteriorates over time, thus reducing the bolt's effective overall length (and thus the bolt's height above the surface), in order not to protrude and puncture or damage tires.
