Screw Selection
Screw Selection
(OP)
We have had an issue specing out our screws, washers, and other hardware. We do not want to have to create prints for everything. Is there one standard I can get that lists the all the specs for the different hardware?
RE: Screw Selection
You ought to show your screws and washers on your assembly drawings and parts lists. If you are creating specification control drawings, you can tabulate them. If you create a list of approved fasteners, you save drafting time, and you simplify purchasing, warehousing and assembly.
What is it you are trying to accomplish?

RE: Screw Selection
You need to prepare specification controls. These provide a complete description of an off-the-shelf part that meets your requirements, and/or a list of approved manufacturers and part numbers. If you can build a list of at least four different manufacturers, you should not have problems with availability.
In the case of screws, you can provide MS or DIN numbers or any other standard that describe your part, and save you having to dimension everything.

That was my initial thought as well, is there an Ansi, ASTM, Mil, or other document out there that gives all the specs for the different hardware. I also don't want to have to buy and maintain a whole pile of specs either. Thanks for all the suggestions.
RE: Screw Selection
There is a Reference Guide I use put out by APC Components, Inc. that shows pictures of hundreds of hardware items and the associated specs:
APC Components, Inc.
75 Toledo Street
PO Box 255
Farmingdale, NY 11735
(631) 249-4079
I would contact them and see what it takes to get the Reference Guide. They are a manufacturer and distributor of
commercial, military, and electronic hardware.

RE: Screw Selection
• All stainless hardware shall be 300 series
• All indoor steel fasteners shall be zinc plated Grade 5 or better
• All outdoor steel fasteners shall be galvanized Grade 8 or better
• Don't buy anything else
Then the Purchasing Dept knows it has to be one of those 3 types.
