Vibration-Resistant Captive Panel Screws


An expanding rubber bushing damps vibration while holding panels together. To install, push the threaded end through a hole in the outer panel, slide on the bushing, and tighten the nut. Next, insert the assembly through the inner panel hole and flip the handle to fasten. They become a part of the panel when installed, so they won't fall out and get lost.
