Great_scot_selfbuild Posted January 11 Share Posted January 11 I have a mixture of different anti-tamper nuts on the fencing clamps I picked up in bulk from another self-builder. Can anyone help me find a socket that will work on the nut on the left in the photo? The person I bought it all off hadn’t needed to use these clamps, so hadn’t encountered the issue (they had bought it all second-hand from a large developer). Currently searching all the usual places (eBay etc). Link to comment Share on other sites More sharing options...
Conor Posted January 11 Share Posted January 11 Can't you just take them off and replace with M14 nuts or whatever? Link to comment Share on other sites More sharing options...

I'm looking at that too, though I'm not sure the socket will fit inside the recessed hole (the nut may just fit, but not with a socket over it). Unfortunately I think I left the clamps with plain nuts back at the site... Link to comment Share on other sites More sharing options...

Search Heras anti tamper @twice round the block Thanks but that's the one I already have (clamp on the right of photo), and seems to be the more common one. The one I'm struggling to find is a socket for the one on the left (different configuration of socket teeth - both width and location). Link to comment Share on other sites More sharing options...

Buy a second one of the type you have and get busy on it with a file to adapt it to fit the other one. Link to comment Share on other sites More sharing options...
twice round the block Posted Sunday at 13:11 Share Posted Sunday at 13:11 This spanner is double ended. Conventional on one end and anti tamper on the other. Am I missing something? Link to comment Share on other sites More sharing options...

The normal end is just a socket (not a different type of anti-tamper). Link to comment Share on other sites More sharing options...

I looked at that, but the one I need has 3 equally spaced slots, whereas the one with a round cotter pin has the 2 square lugs closer together and filing the cotter pin to fit would loose too much metal in the sidewall of the pin.

Great_scot_selfbuild Posted Monday at 23:43 Author Share Posted Monday at 23:43 9 minutes ago, Alan Ambrose said: Pair of mole grips? The nuts are fully recessed into the hole when fitted. It’s like they’re designed to be anti-tamper. Oh, wait… damn their design. I’ve ordered some cheap clamps to see if I can swap out the nut and/or bolt. Hoping the standard socket will still fit when recessed. (These clamps are far more secure than the cheap ones I’ve just purchased) Link to comment Share on other sites More sharing options...
