Hex Head Cap Screws

I am looking for a 5/8-11 UNC Hex head cap screw that is 1" long. The
shortest in the parts library is 2.25" long. Why does it not go down that
low? The old "Insert fastener" command used to have it available.

Thanks. That gets me out of a jamb. Do you assign a part number to each
fastener in your business?

That is the beauty of iParts. You can edit the table to correctly fill out your BOM.

Let me explain my situation and maybe you can help
me use this to my advantage.

 

Each of our fasteners are assigned a sequential
part number.  For instance, all 5/8-11 UNC HHCS are 550030-?.  The ?
is filled in when the part is used for the first time.  550030-1 might be
4.00" long, 550030-2 might be 1.25" long.  Each part has it's own .idw
drawing.

 

What I did today with the iPart from cbliss.com is
to have it calculate the part that I want, then save copy as the part number and
then open the part number and delete the factory and the spreadsheet turning it
into an ordinary part.  I kept a copy of the iPart factory so that I can
use it again next time.

 

Can I edit the iPart factory each time I need a
fastener and put the part number in the spreadsheet somewhere?  Then will I
be able to make individual drawings for each fastener?

Correct, you can add the part number, description etc. to the iPart table so that each specific instance has its own properties. Thats what the member files are for that it creates. I'm willing to bet that Sean in his eternal quest to provide better support than most VARs while not charging a cent has this well documented on his web page somewhere. It is really easy to figure out through the GUI in R6 but if you need help, Sean's site is probably the place.

uggh.. no offense but I would hate to have to use
that part numbering system.  So basically in your system a 5/8-11 x 3" long
bolt has no part number *until* you use it once? 

 

iParts are designed to have part numbers assigned
from the get-go.  You could do what you are proposing but in my opinion it
defeats the elegance of iparts.  Also they are not parametric anymore in
the sense that you can replace a 3" long screw with a 3.5" long screw without
loosing your constraints.

Yeah but he could go into the table and add that new p/n value before he creates that version of the iPart and it would probably work out OK. He would want a place holder for the P/N from the get go. It would be a lot better than un-iParting them.

Yes, that's correct. There is no part number for a 5/8-11 x 3.00 HHCS until
it is used the first time. Not only that, but you may have a 5/8-11 x 2.5
that's released, and a 5/8-11 x 3.0 that's not. You have to have different
drawings for them so that you can keep track of the status of the part.

We had no idea when we created the company and the part numbering system
what size & length of fasteners we would use, so at least I set up a system
where all the 5/8-11 HHCS had a similar number. At the last company,
200005-? represented all hex nuts regardless of size, thread pitch,
material, coating, or anything else!

I was voting for a system similar to what we have now except that I wanted
the dash number to be the length of the fastener. I was over-ruled.

How do you handle it where you work?

We buy all of our fasteners from one source so we use their part number.
Previously where I worked we had a random part number string that
represented the fastener but we entered all of the possible sizes into the
MRP system prior to making any iParts. So I may never use a 1/4-20 x 10"
bolt but if I did it had a part number already assigned.

That would be great. I thought of that, but I couldn't decided where to
stop. 1/4-20 x 10 or 1/4-20 x 8.

What do you do if you need a fastener that's not in the system?

Just wait, some comsultants will come in and tell the execs that each part identity in the MRP has a cost associated with it, thus it is essential that engineering quit putting up new part numbers, and eliminate existing ones. Of course engineering is also supposed to assign a new part number to any part that undergoes a change, and they are supposed to reduce costs. Design one new product that eliminates 5, does everything they did, and costs half as much. Oh never mind just a vent I guess.

We cataloged all of the sizes commonly available. Take a look in a McMaster
Carr catalog. Basically what they have in stock is what is commonly made.
I'm sure someone out there makes a 24" 1/4-20 SHCS but the common size stops
at 6".

If we had a custom bolt we would give it a new part number and would take an
existing ipart and add the length to the table. You could of course also
use your method for this on off bolt.

Rich, we used to beat the consultants off with 2x4s. They did nothing but
monkey up a good system...of course when I consulted I expected my clients
to follow my suggestions (is that hypocritical? )

You think that is bad... We use the vendors part numbers as our part numbers. We are screwed if 2 vendors (screw vs electrical plug) have the same number or if we switch vendors. I have been here 6 months and have tried to get that changed from day 1. Their solutions was to not have any part numbers for bin parts like bulk screws. I guess that is what you get when you let accounting set up engineering and inventory.

Speaking of accounting running engineering, I once put in a requisition for
a left handed tap. We received a right handed tap and found that purchasing
orderd it that way. When we asked why they switched, they answered that
right handed taps are cheaper and it they would not spend the money just so
that a left handed person could use the tool.
