Been having a hard time trying to locate 4mm nylon wing bolts (thumb screw type).. Anyone have a link to where I can buy them?

Thanks

Jimbo

They are not thumb screw type but if you can't find anything else.

If you get really stuck and must have thumbscrews then there's my favourite UK supplier of fastenings, <a href="http://www.modelfixings.co.uk/nylon_screws.htm#thumbscrews">ModelFixings
</a>

Jimbo, I've placed 4 orders with these guys, all took 7-10 days
