Metric screw size for 3.5" HDD

[stealthrt]

Hey all I am looking to purchase some screws from Amazon for my 3.5" HDDs. Issue being is that the nice ones are all M[x] a.k.a. Metric.

 

I know the size of a HDD screw is 6-32x1/4 but I need to know the equivalent of that in Metric. Only thing I've been able to find is a size of m3.5x0.6.

 

These are the ones I am thinking about purchasing: Here

 

So does anyone know what the size it would be?

There is no such thing as a metric 6-32 screw, it is just a 6-32 screw.

 

However if you just want the metric dimensions of the screw they are 3.5052 mm diameter with a pitch of 0.7938 mm

So are you saying a M3.5 would or would not fit my needs?

M3.5 and #6 are slightly different, as far as I know.

If you need to buy HDD screws, you can just search #6-32 screws, which will fit.

No, the thread pitch is different. They can be forced but it will destroy the threads.

If you absolutely need it to work, it will, but it will do cosmetic damage as it essentially retaps the hole and the screw. Nothing catastrophic, but not ideal.
