Right, the thread gone on the plastic nut them. They can't really wear out. What can happen is that they are screwed in to much, then force applied to the lever and it strips the thread out. nI would imagine Gardiners will send you some replacements, but to stop it happening again the twist grip nut should not be screwed in to tight, just tight enough to grip the pole when it is clamped, there should be instructons really as so many seem to strip them out.XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Same happened to me. I stripped the thread. No instructions, now I have read this I won't do it again. Gardiners sent me replacements straight away.
