I'm after some very long screws to enable me to get a grip in an old gatepost I'm trying to left out of the ground.
I've previously used the technique of using the hydraulic lift on my tractor pulling on screws put into the left over bit of post in the ground and it has worked well.
However this gatepost is somewhat bigger than I have attempted before and my biggest (120mm) screws don't give enough grip.
So I'm after something like a big woodscrew to get a grip in this post (it's broken below surface so I can't wrap things around it). Where can I get two or three very big screws?
