Got a name for this part?
« on: October 08, 2011, 11:58:46 am »
I have an Ampeg SVT-VR on the bench. When I removed the chassis from the cabinet two were broken and one was missing... What do you call them?

Here's a better hint...

They hold the chassis in the cabinet with bolts.
The part is the square, somewhat spring loaded insert that resides in the square cutout on the bottom edge of the chassis. They are have a square nut inside.

What are these things called and where do you get them. Local hardware store does not have them.

Thanks!

I THINK you're looking for a "keps" "captive" nut(?)





Or a "retained" nut or a "nut retainer"

Nope. A KEPS nut is a hex nut with a built in lock washer.
Here's a picture.

If you have a Grainger nearby, they have them.

I THINK I've seen them @ Lowes or Home Depot (in the specialty hardware drawers)(?)

Started a search online and it appears they call them CAGE nuts.
I've got Home Depot and Lowes in my area.
Thanks!

I needed some for an Ampeg VL1002 and couldn't find them anywhere but McMaster.  Had to order way more than I'll ever use.  They are 1/4-20.  If you happen to need 1/4-20 I will gladly send you some.....

Tinnerman nuts.

-DL

Nope,

Tinnerman is a manufacturer of stamped steel nuts in a variety of shapes and functions.

While Tinnerman may or not make cage nuts, it really is improper to call one specific type a Tinnerman.

When I worked at Libbey Owen Ford, we'd get in pallets of various Tinnermans, Different part number, different nut, no 2 were interchangeable in our shop.

I used to call the "U" shaped clips that accepted wood or sheetmetal screws for years Tinnermans, until I was corrected

I install them with my channel-locks too! And I cut 2x4s with my skillsaw. Or hang cable trays with Kindorf. Ask to borrow my pump pliers and I may not know what you mean. Or my circular saw? Heck, I got several circular saws, my skillsaw, my dewalt, my tablesaw. Which circular saw you talkin' about? Funny how some brand names become the item name for a lot of stuff.   :icon_biggrin:
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

I'm an avionics tech, we use tinnerman nuts to install instruments like altimeters and airspeed indicators, I've stated more than once that if I even meet Mr. Tinnerman I'm going to kick him in the junk... those nuts love to slip out when you have one had with the indicator wedged up behind the instrument panel, the other hand trying to get a brass screw started(so of course no favours from your magnetic screw driver..)face probably mashed against the throttles... My favourite memory of the Tinnerman nut was standing on a ladder opening access panels under the nose of a turbine DC-3 being the tinnerman nut I just dropped fell through the hole in the floor where the rudder pedals are, and right to where all the control cables run and that plane wasn't going anywhere until I found that nut...

If you know a computer hosting tech, who actually puts boxes in racks, he'll have thousands of them.

Ya know, this post is a perfect example of what's so amazing about this place and the great folks who come here.  We have a brother who needs help with a little, but important, part.  Twenty posts later, he has a multitude of options for suppliers, the proper terminology to know what to ask for, and even direct links.  And along with all that there were some great personal stories.  And not one hater in the bunch - probably because Tubenit didn't post... :icon_biggrin:

Hey Dan, I don't think you'll find them at our Home Depot or Lowes, but Grainger carries them.  There is one a couple miles from your place on the corner of Kimball and Gregory Dr.  (LC and I are from the same area).  Most of the time they don't have what I need already there, but almost always it's in the next morning after I order it.
