Taylor Neck Bolt Size

[Darren]

Hello!

I've managed to run some superglue by accident into one of the threaded inserts in a Taylor neck I have in for repair. I didn't notice until reassembly where I couldn't get the bolt in question to screw back in! I had a look and figured out what happened (looks like the first 2 or 3 threads) so I figured I'd have to 'chase' them with the correct tap to clean them up! Can anybody confirm that Taylor use 1/4" 20 size for these. I've got an inexpensive imperial tap/die set but the 1/4" 20 doesn't seem to fit. I don't have an imperial thread gauge to hand to check so would really appreciate it if somebody could help!

Kind Regards,

Dar

If you have the 1/4 20 die you can use it for a gauge. Just see if it fits the bolt.

Thanks for the reply. Thats exactly what I would normally do but with my cheap set, the die in question looks terrible! The cutting threads won't fit over the bolt but my gut instinct says it's the right one. If I line the tap up with the bolt it looks like the right size. Just worried about making things worse than better. If I can find out the correct size, I can probably pick up a good quality single tap, locally of the right size.

Hi Dar,

I can confirm for you that the bolt used on the Taylor neck/body attachment is a 1/4-20.

That's fantastic Skip. I really appreciate that.

Darren, if the tap isn't working you might try to use a dental pick to remove the glue. If it's only the first couple of threads it shouldn't be too hard to do that then clear with the original bolt.

[Darren]

Thanks Ned. Will try that first.
Cheers, Dar

Internal thread restorer :). Never used it, but this company mostly only sells the good stuff. Never regretted anything ive gotten from them.

Thanks!

i would suggest that you don't use a die to gauge a thread. Use the corresponding tap to compare with the bolt, or even better invest in a set of thread gauges. One other way to clean a dirty thread is to use a little cutting grease or grinding paste on the bolt. Tighten as normal but cleaning tread as you go. Used to have to do this a lot with machinery which used Loctite to keep nuts an bolts in place.

Thanks a lot Steve. Sounds like good advice. Cheers, Dar

Would a q-tip with acetone on it work to dissolve the glue?

[Darren]

Didn't think of trying that either! Thanks, Dar
