Seeking Advice on Nut Sizes for Guitar Input Jacks

I’m currently looking into replacing the input jack on my guitar, and I’m a bit confused when it comes to selecting the right nut size. I’ve seen different sizes mentioned, but it’s hard to figure out what I actually need for a smooth and proper fit.

A Few Things I Need Help With:

  • What is the standard nut size for most guitar input jacks? I’ve read that some guitars use different sizes based on the manufacturer.
  • Are there any specific brands or types of nuts you recommend? I want to make sure I’m not just getting something that looks good but actually works well.
  • What tools do I need to work with these nuts? I’ve got some basic tools, but I want to ensure I have everything needed for the job.

My Current Setup:

I have a Stratocaster clone, and I’m trying to improve the connection stability. It’s been giving me intermittent issues, which I suspect is due to either the wiring or the jack itself. I’m hoping that replacing the nut can help.

Any Advice?

If anyone has experience with this or could point me in the right direction, I would appreciate it. I’m particularly interested in brands known for quality and whether there are any tips on installation.

Thanks in advance for your help!

When it comes to guitar input jacks, the standard nut size is often around 9/16 inch or 14 mm. Make sure to measure the threaded part of the jack to get it right!

That’s good to know! Are there variations based on the type of guitar? I’m curious if electric and acoustic jacks differ.

4

Electric guitars usually have a 1/4 inch input jack which is also pretty standard, while some acoustics might use a slightly larger one. It’s best to check the specific model to be sure!

Interesting! Does anyone know how to accurately measure nut size if I don’t have calipers?

6

You can use a ruler or tape measure! Just make sure to measure the diameter of the threaded part. Don’t forget to also check the depth if you’re buying a new nut.

Thanks for the tip! Do you think a digital caliper is worth investing in for these kinds of repairs?

Absolutely! A digital caliper offers precision and can save you from making mistakes. It’s useful for various other measurements, too.

Is it just me or does measuring nut sizes feel like an exact science? :thinking: I mean, every millimeter counts!

Exactly! I tried using a small wrench once and it ended poorly. :joy: Better stick to proper measuring tools!

That’s a great reminder! I’ve heard many horror stories with DIY repairs. Anyone ever had a complete nut replacement disaster?

Oh, I’ve been there! I once stripped the threads completely. What a pain to fix! Make sure to take your time with it!

Yikes! Note to self: don’t rush! So what’s the best advice for a newbie tackling their first input jack replacement?

15

When it comes to nut sizes for guitar input jacks, compatibility depends largely on your guitar’s specific model. Most input jacks use standard nut sizes, but variations exist. It’s best to check your guitar specifications first.

16

I’ve found that using slightly larger nuts can work if you use washers for better fit, but it might be a temporary fix.

17

Is there a specific nut size that is more commonly recommended for strats? I want to make sure I get the right one!

18

For strats, a 1/4 inch nut size is typical for input jacks, but it’s always good to double-check with your guitar’s manual.

I once used a 6mm nut when I needed a 5mm one, and it worked after some adjustments! Just make sure to test it out.
