I just got some of "Raul's" clamps to use on a 3/4" baltic birch tower box. The bolt that attaches the clamp to the enclosure is too short for my box. They appear to be metric M10-1.5 socket bolts, made from A2-70 stainless steel. I need at least a 30mm length, and want to buy 6 of them.
I've emailed Rio at PMM but haven't heard back from him yet. I checked Home Depot but couldn't find anything similar. I found BoltDepot.com but they want $10 just for shipping: http://www.boltdepot.com/product.aspx?cc=25&cs=81&cm=19&cd=1319
Do local hardware stores carry bolts like this? Is there a cheaper online source?
