screw and bolt gauges

[pinball god]

Can anyone recommend a good low cost gauge system to help id screw thread types, lengths etc so people can confidently buy various bits of fastening hardware for pinballs? At the moment it is very much hit and miss for me.

You could use a piece of plate steel with drilled holes for the bolts to just fit.
All the USA manufacturers use UN threads, #4, #6, #8, #10, so you only need four drilled holes.
Be aware though that Australian or European manufactured machines may have metric threads.
For example Gottlieb machines made under licence by Vifico in Spain will have metric threads

Rob - Bring in some screws and we will see how the gauges can e used - we don't have many left, but I've got some coming in the next big USA shipment.

Another pain is determining the length and head type. When looking online you can easily make mistakes.

Don't shoot me for this advice, but most cheap tap & die sets have thread pitch gauges in them eg http://www.irwin.com/tools/taps-dies-sets/thread-pitch-gauges
You can buy the gauges separate, probably on eBay...

I've got metric and imperial ones and they are excellent - some threads are very similar and sticking the guage on the bolt verifies it 100%
