Bobzy20 Posted June 23, 2010 Share Posted June 23, 2010 I’m currently following this tutorial I found on YouTube and drawing it in AutoCAD although the video shows it being drawn in SolidWorks. I come to the point where the user inserts an M14 Hex Bolt (ANSI B18 2.3.5m) Hole which I don’t think AutoCAD has a library for and really wanted to know the hole size? Maybe its starring me in the face but the ANSI figures above seem too small. Does anybody know the correct hole size? The user inserts the hole @ 5:18 on the video Any help would be great. Thanks Bobzy20 Quote Link to comment Share on other sites More sharing options...
H'Angus Posted June 23, 2010 Share Posted June 23, 2010 Well an M14 bolt is 14mm diameter, therefore the hole size would be between 15 and 17.5mm diameter depending on the required fit. Quote Link to comment Share on other sites More sharing options...

JD Mather Posted June 23, 2010 Share Posted June 23, 2010 Your Machinerys Handbook or any mechanical drafting text will have this information. Tap drill sizes are also available on many sites on the internet - a quick search should return a metric chart. Quote Link to comment Share on other sites More sharing options...
nukecad Posted June 23, 2010 Share Posted June 23, 2010 If you can't afford the Machinerys Handbook then take a look here- http://www.roymech.co.uk/ (I must get round to thanking Roy for all his good work). Quote Link to comment Share on other sites More sharing options...
