I took six tight bolts off a washing machine for someone. He said they were tight and would probably snap out. They did


Anyway, I cannot get any.
They are M8x18 left hand thread. (Probably high tensile steel). I need six of the bleeders. Anyone know where I can get some. They are out of stock at the usual spares places (espares etc) and cost about £5 each anyway

Any help much appreciated,
Thanks
Keith
