Standards for Bolts and Nuts

11/09/2008 6:40 AM

Hi all,

Do you know a useful website that holds good detailed info on Bolts & Nuts?

The ones I could locate through google were worthless and I need something detailed for references.

thanx

You should buy a machinery handbook.

Although there are individual ANSI, ASME, etc. Standards covering screw threads and each type of threaded fastener, the most comprehensive book of fastener standards is "Fastener Standards", published by the Industrial Fasteners Institute. Take a look at www.indfast.org and find it listed under "technical books".

I see they have now separated inch and metric threads and published two separate volumes.

If you work for a company, you might talk them into purchasing whichever is applicable (or both if you deal with both). On the page referenced above, you will also find individual standards for different types of bolts and nuts.

Along with the reference books (that should be used for parts development and bolts/fasteners design), if you're interested in fast references for available dimensions and commercially available options, as well as usefull models to include in drawings, I recommend you to take a look at hardware supplires sites like www.mcmaster.com . search for what you want, and its most likely that you'll end with a 3D model of the item.

Re: Standards for Bolts and Nuts

Thanx Kev,

There are a lot of good infos just need to get through them all.

I basically wanted the dimentions on bolts mainly like:

diameter, depth of thread, head sizes of: countersunk, hexagonal, round (cross recessed) and so on wrt their size.

For reference to know what size pre drilling (fo threading), counter-sink tools, nd torx or philips heads to use.

There was an excellent handbook on my last job but I never saved (copied) some of the important pages from it and now I am struggling.

Hi, Kev,

I'm Ari (Orpheuse) and I really thank you for that post. I've been dealing with robotic modeling for a while now and finding a specific nut or bolt, and the socket driver for it, has become a real pain.

I live in South Florida (yeah, we got it right this time), about 10 miles East of the Everglades, which, in other words, means I live in "Swamp Castle". Finding things down here is a 50/50 at best: at worst, your chances are Slim and None, and Slim left town.

What you have just given me is the vocabulary to intelligently ask for what I need.

You have my most sincere thanks and admiration. Don't stop, you're doing a good thing, and for that, you get <Ta DA> another point.

Sincerely yours,

/Ari (Orpheuse)

Hello Kev_brown:

I had it said to me a while ago and now I am saying it to you..................

Very well done for the research and the thought put into the post. There is a lot of work there, very well done!

Take care.....................

Hello Orpheuse:

hope you are well in 'swamp castle'?

I gave Ken Brown I think, sorry I am terrible with names" Anyway, I have given Ken a point, if that is what you meant?

He got in there before me!

Take care...........

For articulating the mechanical design I use the library that is integral with my SolidWorks software.

For determining performance criteria I have been a devoted user of the Machinery's Handbook for over 35 years.

I too find that McMaster's website is a very fast and convenient resource for supplemental data. Occasionally I will use their 3D library but cautiously.

Regardless of format (STEP, IGES, etc) their neutral files often generous enormous part files when imported that burden a CAD model needlessly. They can be used but care should be exercised.

Also check out Umbrako and Holo-Krome. They seem to have good info in their catalogs.

You may also refer to SAE standards, which gives data for wide spectrum of Nut Bolts.

Dear Isti 80,

I think KEV has covered most of it. I have been been using DIN HAND BOOK 55.

Fasteners 3 - Technical Delivery Standards for Bolts, Screws, Nuts & Washers-

Paperback Edition 3. Deutshes Institut Fur Normung E. V ( German National Standard )

01-Oct.-2005 / 544 pages. This contains all 32 Standards & provide information

on the Materials, Mechanical & Functional Properties, Dimensions & Tolerances

on the parts.

Hope you will find this also useful.

P.Rangasamy.

You just hit the nail right on its head.

It was DIN book that we used to have at work (metric only stuff) but that's what we needed.

Where do you think I should start to find it?

It seems that you were not born, but you were turned and threaded and tapped to bring in to existance.

You seem to think that you are the ONLY one (I won't say person, as you were not born) who knows about the threads in whole of the globe.

Your name must have been Screwshersigh instead of Shamshersingh, but you are playing your Shamsher on every body.

Oh nut, do not screw all others.

Dear guest , its surprising to hear such words on this platform where you can share knowledge....i hav gone thru your comment straight to me ...i m surprised peoples talking this type of language also are there...on this site...,

how u came to that decision without having technical discussion with me regarding fastners engineering....being born into means since childhood and from forefathers i m into fastners....it needs balls to say that i m master in that field b cause i have to answer any question...

sorry my dear frend you hav no right to spoil anybodys reputation by using those words....online which everybody can see....whnever u want to proove ,prove by technical discussion, by economical discussion..discuss...how to save manpower,how to grow production,how to save energy, what should be research and development in fastners.....o k..........
