To save myself some time, I bought a NAS with no hardware to screw 3.5 hard drives into the bay before loading them into the bay. 4 failed attempts and a return of the diff screw, that will help you. These screws work with the NAS hard drive tray and are flush with the hard drive to fit seamlessly into the bay.
