Thanks, i'll try that. Re-reading my posting it occurs to me that there could be all sorts of innuendo, but I did mean the sort you put in with a drill. In the ground!
I use Wurmi plastic type. With the fitting for a cordless drill it's very quick and easy ( and lazy ). I've found them brilliant in all types of ground.
OK, so i got my srews etc from screw fix, as has been discussed, but how do i enable my cordless drill to screw them in. Where do i get an attachment from to fit the drill and a 13mm hex head ?
