Yes, you heard correctly, free engineering data!

I have been meaning to post this for a while, but finally got around to it.

There have been a few times where I have been working on something.  Then found that I need information that is not readily to hand.

So, where do you look on the web for free engineering data?

Manufacturers’ web sites are useful as they may give dimensional data. Some are now supplying 3D models in a range of formats.  There is also a site where manufacturers’ can post models for engineers to download.  You have to register, but this has proved useful.  The site is TraceParts

If you cannot find a manufacturers site then try RoyMech.  Covers mainly British Standards areas.

If  you need SWG equivalents, there is a very nice chart on The Engineering Toolbox.  Calculators for various engineering functions are available as well.

Another site for information such as ACME thread data is Engineers Edge.  Also has an engineering supplies and book shop as well.

For stainless steel, the British Stainless Steel Association has an excellent website.

Sadly the Copper Development Association in the UK apparently no longer exists. Not sure if the handbooks on copper and brasses can be downloaded now.

If you need data for an FEA program then MatWeb  may be suitable.  Although UK specifications can be hard to find.

Wikipedia also contains some information on engineering subjects.

Some of my customers have found the sites helpful.
