ABSTRACT:
The present invention relates to HDD screws, and more specifically to lubricating the HDD screws. HDD screws may be coated in a layer of a PFPE based lubricant to reduce friction while fastening the screw into a HDD. In addition to providing superior lubricity and reduced friction during fastening and longer shelf life, PFPE lubricated screws provide narrower clamping load distribution and lower particle generation compared to currently used screw lubricants. Furthermore, because PFPE lubricants are also used to lubricate magnetic disk surfaces, the HDD screws may provide a reservoir for replenishing depleting lubricants on the magnetic disk drive surface.
