Sizing Bolts

[Mike.C]

I seem to have lost a few bolts from my router table insert. How do I size the remaing one so that I can order some over the net?

Cheers

What's your router table insert? Who made it?

Is there some place locally that sells hardware like that? Perhaps you could take one with you and find a match. If it's imperial stuff and you can't get it locally, I can probably help you out.

You measure the diameter over the threads with a micrometer or vernier caliper and determine the threads per inch or pitch in millimeters, the latter (pitch) best done with a thread pitch gauge as this also confirms the thread angle and then look up the details in a thread standards chart Such as This.

All else fails go into your local DIY Shed and try to find a nut that fits your existing bolt.

Chas, Dave thank you very much for your replies. After a few measurements I was able to get the bolts I needed.

Cheers Guys
