Dodgy bolts
I posted this on a car forum I'm on , might be relevant to some people here
hopefully your all aware but for those with trailers and general info........ Just happened I was in the Bolt shop to replace a Chinese Crankshaft bolt that broke. This was a metric bolt marked 8.8, it snapped inside the crank after 2 hours work. This thing drilled like real soft mild steel, had a chat to the bolt guy and he mentioned the Chinese bolts that are supplied with the Chinese trailer couplings that are out there. These are also marked 8.8 but are an imperial thread , so incorrectly marked for a start. They were also poorly threaded looking to be offset somehow, his opinion , poor quality mild steel rubbish. So I'm saying don't use ANY but confirmed non Chinese bolts anywhere where safety is a concern. Don't know if anyone like Roads and Maritime, or whoever is responsible, will order a recall or care but Id rather not read of an accident on here caused by cheap nasty bolts.
