New Thread about Randall RG80 type amp chassis mounting screw threads

[DrGonz78]

I have no idea what you even call these things... But those mounting screw sockets found in the Randall amps from the 80's are very hard to find. You know those little brackets that accept the screw as to hold the chassis into the cabinet. Well, what are they called and how do I find one? Any help would be greatly appreciated. One of the brackets is stripped a bit and I cannot for the life of me get that one screw tightened up correctly. Maybe there is something that I could do to fix the threading?? Just not sure where to even find things like this... Thanks for any ideas in advance.

Oh of course I search for this for a long time and did not find what I was looking for... Then I post some silly thread about threads... Then I curiously typed something into a search engine and found exactly what I was looking for... CHASSIS CAGE NUTS, MARSHALL M6 METRIC. So I found something to go by and find at least something that resembles what I am looking for parts wise. But my question still stands as to where you all look for parts like these ones.

Places that sell amp parts.

Guitar, Amplifier, and Korg Keyboard Parts | NATIONAL PARTS DISTRIBUTOR FOR KORG, VOX, BLACKSTAR. PARTS FOR FENDER, GIBSON, GRETSCH, HOFNER, SWR, GUILD, AND MUCH MORE probably has them

And for ANY piece of hardware, look at McMaster-Carr.


Decades ago I bought myself a basic tap and die set, then a metric version. Not particularly expensive, got the little kits at Sears. I use them almost exclusively to restore stripped threads. If I have a ruined cage nut, I can replace it many times, I do stock a few sizes. But sometimes I put a head back together and the last screw was crossthreaded at some point. The nut may be stripped. I also look at the bolt, it may have rounded off threads. One bad screw over time will infect every hole in there, most of us don't keep track of which corner screw was in which corner.

I have three tap handles sitting next to me with common thread size taps in them, the rest of the kit is nearby.

SO I determine the thread - 6mm, 10-32, whatever. I can hold the bolt up against a thread pattern or just a tap thread. Now that I know the thread size, I run a tap through the stripped nut, and most times it restores enough thread to make it work again. I run any rounded thread bolts through a die to bring their threads back into focus. And I can do that while the amp remains in the cab.

Personally I go to GATA, "THE screw house" in Buenos Aires.
What they don't have, doesn't exist
Unfortunately not much use for you.
I know there are quite a few fastener shops in USA which really carry *everything* but what you need is very "Musical Amp" specific, so I'd search specialized shops.
Try the usual suspects.

Yup Parts is Parts is a great place and I know to ask if they don't display the product. Also, very interest about running a tap into the stripped nut and may give that a shot as I think it is the nut. Will probably buy extra of these parts for future use...

"The Screw House" mmmmmm sounds warm and inviting!! lol. They have a fit for all the shaft sizes your looking for... But seriously I wish the hardware stores around here had way better selections for when it comes to amplifier parts. Yup these parts are a tough find!

Thanks for the input this helps in many ways
