Nut doesn't go on bolt

Post by alan412 » Tue Apr 28, 2015 2:16 am

(Please excuse my ignorance. This is way out of my mechanical comfort zone, and I am hoping I can get this all together.)

For one of my M8 bolts, the nut won't go past the first spin or two. Any suggestions?

The bolt supplier accidentally mixed some 5/16 nuts in with the 8mm nuts. It's not your fault. I am not sure what the long term solution is but in the short term any hardware store will have an 8 mm nut.

FWIW, that was mentioned in a post of mine where I answered your asking after the instructions: http://www.shapeoko.com/forum/viewtopic ... 485#p45485
- count carefully and identify things first, testing all the parts. Brandon and I were short 2M5x16s, and Tim and I had some 5/16" hex nuts mixed in w/ the metric ones — if something doesn’t thread properly, don’t force it, investigate. You want one list of parts, for one trip or package from a Edward, not the 4 which I wound up making (see the Makita mount posts for details on the last 3)

@WillAdams,
Please be patient with me. There were a lot of helpful comments (more than I can remember). My first inclination (being a software and electrical guy) is that I am doing something wrong, not that there is a problem with the parts.

Understood. Just trying to be helpful. My apologies if it didn't come across thusly.

This parts issue is absolutely bizarre --- it was Tim Foreman who reasoned out that it was Imperial hardware mixed in w/ the metric --- which I was able to verify when I went to the hardware store to replace the M5 hex nut I'd managed to misplace (not looking forward to finding that w/ my wife's vacuum cleaner....)

Will - You may not have misplaced that nut - I appear to be 1 short as well. I am currently short on 2 m5x16 BHCS as well...maybe they will turn up

No, I misplaced it. I counted two, three times and it was right, then I got to the last fastener and was missing one nut.

Tried counting parts on the machine and couldn't get it to come out to being 1 short at the original count --- I lost one.

That said, there have been a number of instances of people being short (which Edward has been making good) so if you've counted and you're short, you're short --- hopefully we can get the kitting process to work better. My inclination would be to just round everything up by 1 or 2 or so, but it's not my budget.
