Day 406, Coach bolts, the fastener of choice for the discerning constructor
If wood is your material of choice, and you are dealing with substantial building then these are your fasteners.
Fasteners are great.
Aren't they.
Aren't they?
Well I think they are.
Harrumph.
Choose the size of fastener to fit the application, the data sheets will help.
The larger bolts here are bog standard, mild steel, coarse threaded M8 sized bolts.
Coarse here means they have a thread pitch of 1.25mm and 20 threads per inch.
Mixing units is common when referring to bolt dimensions. All metric would be simpler.
The smaller bolts are M6, although they appear much smaller and the threads per inch doesn't look right at all for that.
Perhaps they are rogues placed there to disrupt the fastener zen.
I have nothing against the 'M6' bolts, I welcome them to my fastener menagerie.
Even though the 'M6' bolts aren't as shiny.
