Hole wizard is a very powerful tool, if you ever used earlier versions of SolidWorks without the hole wizard (me) you can really appreciate it. What this discussion points out is not SolidWorks Hole Wizard problems but how many variations of "Standards" there are out there that vary from industry to industry for threads and hardware. There are a lot of options and functionality in the Hole Wizard because there has to be. We just have to make sure we click and choose the right ones. Tom

Some of us use it everyday. You can find 100 deg countersunk screws from any aircraft hardware supplier as well as general hardware company the sells to the military or aerospace industry.
From: Keith Streich on 7 Mar 2007 15:16 It just so happens I ran across a inconsistency with 1" UNF specs today. I specified a 1-12 UNF and Fastenal replied there was no such animal. My old slide screw and nut calculator said 12 tpi, SW popped in a 12, but Fastenal, McMaster and Reid all say 14 tpi. The funny part about the SW is if one uses hole wizard, it's a 1-14, but toolbox has no 1-14 threaded fasteners. I'm using SW2K7 SP2.0.

Finding knowledgeable sources where threads and threading is concerned is hit or miss. Seems Fastenal, McMaster and Reid are a miss. I hope when you say Reid it is a seller of hardware and not Reid the Thread Rolling Company. Looking at Machinery's Handbook an older version (21) They have this for a 1" thread; 1-8 UNC 1-10 UNS 1-12 UNF 1-14 UNS 1-16 UN 1-18 UNS 1-20 UNEF 1-24 UNS 1-27 UNS 1-28 UN 1-32 UN Then there is the little note on the bottom; "Use UNS threads only if Standard Series do not meet requirements." So it seems 1"-14 is NOT the standard......go figure. I hadn't known about their being no 1-14 threaded fasteners in toolbox. You can bad mouth "toolbox" but leave the "hole wizard" out of it.......LOL. Tom |
