Dave, thanks a lot !!!

Your answer is too good for me comming from THE engineer of Hawaii ( just this makes me dreamming !! )

I found my contribution to this exellent forum normal as I'm already learning a lot every day ( and I'm using AutoCAD every day at work since AutoCAD R13 - 1995 ).

Without answering at every discussion I read all of them and learn a lot.

This is what really is best about this particular discussion board... what one might call the "Value-Added Posts". Folks here don't just answer the immediate question at hand, they anticipate and provide that extra measure of useful information.

Great answer, Philippe! Thumbs%20Up

Hello, the bolt that you are talking with the "callout" 5/8-11 UNC 2A doesn't include the length.

5/8 means the diameter of 5/8 x 25.4 = 15.875 mm

11 means 11 threads per inch # 25.4/11 = 2.3090909... mm pitch

UN means UNified ( american standard )

C means Coarse ( standard big pitch versus Fine pitch )

2A means the tolerance of the fabrication ( standard )

The length of a 5/8 screw ( bolt = screw + nut ) is between 1" ( 25.4 mm ) and 6" ( 152.4 mm ) including :

1" , 1"-1/8 , 1"-1/4 , 1"-3/8 , 1"-1/2 , 1"-3/4 , 2" , 2"-1/4 , 2"-1/2 , 2"-3/4 , 3" , 3"-1/4 , 3"-1/2 , 3"-3/4 , 4" , 4"-1/2 , 5" , 5"-1/2 , 6"

You should also specify the material for example : Steel - Grade 5

You should also specify the "state fo delivery" ( protection )

Ask for more; you should read more informations about Unified Thred Standard on WIKIPEDIA or on school books if available for you.

I have an old example in PDF form of "CLARK Equipment" bolts standards that I can send to you on request.
