Did you also sometimes wonder how many kinds
of different screws are around in the world?

Everything is fixed with screws and if you
need a replacement screw, you don't even
know what's the name of this screw?

To avoid any misunderstanding in a spare
part store or in a DIY market iscrew
let you identify your screws quickly !

Just compare the pictures with your original
screw.

iscrew informs you about the deep unknown
screw space in a very easy way.

No you can impress your friend by asking

Slotted 6 Lobe Combo screw for me..."

Or just learn something about
screws you never learned before
