I have just bought and fitted a Nemisis Ultra wheel lock, it looks like a good bit of kit, it was easy to fit and it's a doddle put on and take off. However I noticed that the replacement receiver wheel nut is substantially bigger and heavier than the standard nut which makes me think it may throw the wheel way out of balance, (even though it hasn't been balanced initially)? My thoughts are maybe as it is in the centre of the wheel it won't have a centrifugal effect, I am concerned it will shake my fridge about and turn my milk into butter..

Do not fear. I've had mine fitted for 4 years now and all is well. Colin

I mentioned this to Nemesis last year when I was talking to them about a lock issue. They had not thought about it.

If The bolt is about 25g heavier than the others and the bolt is 112 mm from the centre, this would be equivalent to around 8 grammes on the wheel rim; hardly a bone-shaker but not properly balanced either.

I had my wheels balanced as soon as we got the new Troll home last year, they needed 40g to put them right; caravan manufacturers don’t seem to think it’s an issue but we’ve had screws and doors shaken loose in the past until someone suggested the balancing.

I guess the alternative is to fit 5 security bolts to each wheel. (You’d get away with 2 on a 4-bolt puck.)

BTW, we had a lock on both sides so double wobbles?
