HelloIts me - neighbour. Actually Im new here and I came to ask a question. Im not a technical drawer so doing CAD drawings is not for me BUT I study mechanical engineering - just not this part for which the forum is.My question is if anyone has any experiences with either drawing or recognizing the technical 2D ( ! ) drawing with bolt/screw? The problem is that I have three technical 2D drawings (not yet attached to this post), all from the same bolt type but what I need to do is to recognize what does each dimension mean. Of course dimensions like diameter and length of shank, diameter and height of head, angle of thread, thread pitch (and perhaps something else too) are easy to recognize and ''name'' them but some of definited dimensions are pretty hard to name and I have no idea what they mean but I have to define them.It wouldn't be much of work - together would be about max 10 dimensions (unknown to me) to name - so what do they mean.So if anyone is willing to take 5 or max 10 minutes, I would appreciate. I have almost any instant messenger. I can also install requested one.Thanks and hope someone can respond.

You're talking a metric screw right?

John thank you for reply. Yes classical M bolt. Or if you/anyone can suggest me some literature that would help me naming the dimensions would be good too. But literature probably shouldn't be just such as ''CAD For newbies'' because its too general. Even if I found some 2D drawings of bolt/screw online it would help because nowhere are names/explanations (at least not ON drawings) what the specific dimension/size/length/whatever means.

hello?

I found this information by searching on the terms "metric screws"+"terminology".http://www.zytrax.com/tech/mech/threads.htmMiscellaneous data re: metric screws.http://icrank.com/cgi-bin/pageman/pageout.cgi?path=/data/screw/metric/screw_metric_source.htm&t=2http://www.metrication.com/engineering/fastener.html

The links aren't really related to what I meant with ''naming the dimensions''. I have uploaded to the following link first out of three drawings:http://img.photobucket.com/albums/v309/Andreii/drawing.jpgOn this drawing I made 5 blue circles. Those are the dimensions that I would like to know what do they mean?For example the name of dimension "10" is of course ''Length Of Shank''. And name of dimension ''M4'' (4) is undoubtly ''Diameter Of Shank'' and so on.But those 5 blue-circled ones aren't so obvious, at least for me not. So I need to name them. For the close-up view (zoom), I uploaded the jpeg file also:http://www.sendspace.com/file/pnj8kb

Sorry that the links did not provide what you are looking for.Have you visited the local library lately?  I don't think they have burned all the books.  LOLR6.2 is a radius.~0,3 looks like the depth of the teeth.The other two I don't know.What type of bolt are you showing?

Radius of what? Probably head's radius but this is not really pro-said... Yes I made the mess in almost any technical library but no luck (yet).Its M4x10 (no milling).Do you know anyone who I should contact?

What TYPE?  I don't recognize the head on it.Don't you have access to a standard of some kind?  Not sure who publishes the standards for bolts and screws in Finland.

Its M metric type (with thread).

"Type" such as: pan, hex head, socket head, socket button, etc.What you have given us is the nominal screw diameter and thread pitch.
