Hi Malcolm,

Many Thanks for the question, there are a few ways to do this, One is to saw or angle grind the the protruding screws off. But this leaves the lock easy to break off as its not being held much. My preferred way of doing this is to have a piece of 4″ by 2″ wood about the same size as the hasp, And place this inside the shed behind where the lock will be. ( you can either get someone inside to put in place once they see the screw coming through or if you drill pilot holes for the screw first you will see where it is supposed to be) Then screw each screw in turn ensure it is going into the piece of wood of 4″ by 2″ inside. Once finished on the Hasp, Do the same for the staple, ensuring they line up. When finished the pieces of 4″ x 2″ should be tight to the shed wall and screws are hidden inside.

Hope this helps.
