Hi all
I have a left of field question.
Does anyone know what these markings on the head of a bolt mean.
IE strength etc.
It is a metric thread (M12) 100mm long and is bright coloured (I would normally call it zinc)
It has the following markings
B
D2
M or a W
cheers
The other bolt is shorter, black and has an 'x' and 8.8 which I take is a metric high tensile.
Cheers
