Having looked through amazon and this forum looking for the perfect lock I have found one for a price on amazon that I can spend at the moment.
I am after advice on how long this specific lock here:
https://www.amazon.co.uk/Padlock-Garage ... B00C1SDCZ4
might hold up to an attack from a grinder or lock picker or hammer smashing hooligan?
It is being used to hold two bits of chain together connected to a ground anchor which is subsequently wrapped around the front axle of my car.
Please offer any other suggestions of locks that are from £10 - £35 available in the UK that might be a better bet if you have any! It will need to have a shackle large enough to fit round a 1cm diameter chain

Thanks for the help!!
