I have a Seco brand UFO-101 dust collector that I purchased off of craigslist a few years ago. I looks pretty much like any other ~1.5hp ~1000cfm offshore single stage dust collector. (think harbor freight type) I retrofit it with a canister filter from Wynn Environmental, and it’s been indispensable.

Yesterday, while sanding over the downdraft table, I heard a thunk clank tink tink tink whrrrrr grrr from the dust collector, after turning off the power and convincing my wife I still had all 10 fingers, I found the bolt that holds the impeller to the shaft had come undone, and the key stock and washer were missing.

Replacing the key and washer will be easier enough. But, the bolt is mangled and bent and will need to be replaced.

I have named this bolt the impossibolt. So far as I can tell, it’s a 30mm long M6-1.0 metric cup head bolt with a left hand thread. I can’t find one anywhere on the internet. All of my usual go-to places for hard to find hardware… bolt depot, mcmaster… nothing. My last hold out is the best damn hardware store in northeast CT, which I’ll try in a few hours, but I have my doubts.

Does anyone have any ideas? Or better yet, does anyone have a broken down old Seco UFO-101 they want to sell me for the cost of a bolt?

Intriguing request, Chuck. I Googled left hand metric bolt and got several hits, but no way to check inventory without making some calls.

I think it’s out there, but you’ll have to do a little phone work.

And I really like your neologism: Impossibolt. Right on.

If bad comes to worse, you can always drill & tap it to a standard thread … even a right hand one, and use a drop of red LOCTITE on it … it won’t go anywhere, and it will be a fast & easy fix.

OK, I found the bolt. I still couldn’t find it online anywhere, and any brick and mortar store just directed me to try looking online. I did end up e-mailing the manufacturer, Kufo. They e-mailed back promptly, they knew the part I spoke of, and I called and ordered it. I was a bit pricey for a bolt and washer (6.95 plus 9.95 shipping) but it was easier than drilling and taping, and cheaper than buying a new dust collector.

The new bolt will be installed with some threadlocker to avoid this sort of thing in the future.

Thanks for the input folks!
