Ultrabay Security Screw Specification (W700ds)

[LavaChild]

Hello!

I would like to install the Ultrabay Security Screw on my W700ds however I do not have one. I have am having a hard time finding one to purchase and would like to avoid dealing with Lenovo direct (I can only imagine the cost for a single screw).

Can anybody recommend another source of the screw? If not, does anybody know the specification of the screw - I'm sure I could locate one elsewhere in that case. I know it has a hex head. Not sure about the length, diameter or pitch, though. Any help?

As an aside, if anybody has an unwanted one please let me know!

Thanks!
