Bolts - Finding sizes

[GJUK]

Good morning.

 

Right, I'm convinced this must exist or at least be possible to create.

 

If one had a 'random' bolt, and you wanted to find out the size, and thread type, is there such thing as a real scale diagram where you offer up the said bolt to the large diagram, and match it to the picture of the bolt in the picture so you know what to order.

 

Now I know everyone has a bucket of random bolts they just find the right one they need. But does this diagram exist?

 

Thanks

Measure the outside diameter and the pitch and look in a Zeus book

there is something called a pitch guage, its like a set of feeler guages but with teeth on the side, you use them to find what thread you need then use a vernier caliper to measure the thickness of the bolt

hope this helps

pitch guage is often part of a tap and die set, spose you could truy the bot in the taps of the set to find out.....

Can I lay you flat on my desk and place bolts upon your being?

I guess you're not A3 size and as thin as paper. Nevermind.

 

Thanks for all the advice everyone.
