Dear Friends,
Help required in identifying the major bolts used in cg-125. I am more interested in crankcase covers, cylinder head, chain cover and frame bolts etc.
I am asking because I may go for higher grades alloys or chrome ones.
On workshop manual some references are available like M6, M8 M10 etc.
I know that
1) Bolts are Hex
2) M stands for Metric measurement system
3) 6,8,10 etc is bolt diameter or its thread diameters
What I could not understand is that:
1) whether all the bolts used have coarse or fine threads.
2) Does threads have standard spacing as mentioned in online helps. e.g an M8 has 1mm thread spacing and M10 has 1.25mm thread spacing etc.
3) How to get the length of the bolts.
4) An online parts catalog that shows all the details says bolts used on crankcase covers are 6*32. What is this measuring system.
Need you valuable inputs.
