What is the correct name for these clips?

[wa3lkn]

I think I've seen these used with screws to hold down transformers on older radio chassis?

Any other ideas?

Tinnerman nuts.

[KE6SHJ]

These are used in the automotive industry. Clamp locks. Used to secure radiator clamps, transmission harnesses, etc etc..:)

Yes, but do you remember Fahnestock clips??

I not only remember them, but I used to date Peggy Fahnestock (from NJ, where I'm also from) as a teenager....I think she was the granddaughter of the guy who invented the clips.

Their purpose seems to be to raise my blood pressure when working on my vehicles. They always fall into the fender or strip out when i deal with them.

Made me so mad one day I got out the rivet gun and permanently fixed my problem.

[WA2ZDY]

YLV, "hooking up" meant something very different back when Steve was a teenager. Or when I was a teenager for that matter!

MRQ, yep, you've fixed it alright. Until the next time you need to pull that piece out of your ride.

What is their purpose? "Some" security for areas where a light fastener will do in a spot not easily accessible with a wrench.

Fahnestock clip
Originally a high school sheet metal shop test project, it was allowed to escape captivity at the turn of the century, since when it has often been sighted lurking in elementary school science classrooms.

Chris is mostly correct. The purpose is that the Tinnerman will clip onto a flat surface and remain in place without moving, or being held, negating the requirement of having three or even four hands to hold a nut, hold a piece of equipment, AND install a screw to mount said piece of equipment. The drawback is that they are not the most srurdy fastening device, and can often be overtightened and stripped, rendering the mounting useless.

(And I haven't seen Fahnestock clips since I packed away my Lionel trains...)

[KB1NIV]

I still use Fahnestock clips for breadboarding projects, they are a nice way to make temporary connections while testing component values in a circuit or modifying the circuit on the fly to see what happens. I guess with modern IC and SMT technology they became obsolete.

Maybe we should patent really, REALLY small Fahnestock clips for work with sudface mount devices? http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif http://www.qrz.com/iB_html/non-cgi/emoticons/laugh.gif http://www.qrz.com/iB_html/non-cgi/emoticons/laugh.gif

I've seen that type of T-nut used in 19 inch equipment racks, but I have also seen a type that uses an actual nut that is fastened to the spring portion. These are especially used for the real heavy stuff that required two or more people to lift into place, and for some reason, were always placed at eye level or above in the rack ! ! ! Those things would have torn the center out of a standard T-nut such as those pictured!

Ahhh, the good old days !

Tinnerman makes sheet metal nuts to order for big buyers. Not all are u-shaped. I have a large assortment. From the coarse pitch shown yours are probably for sheet-metal screws, but all kinds are made. Tinnermans can be very useful. Sometimes I glue them down to hold until the screw tightens.

This is my wisdom for the day, back to bed.

Sure, we use clipnuts and cagenuts for this (rack cabinet equipment installs), they are much stronger than Tinnerman nuts and are available in 10-24, 10-32, 1/4-20, 1/4-28, M5 metric and other popular sizes.

I met Peggy Fahnestock in college. Her last name rang a bell so I asked if she was related to the "clip" guy and she told me it was her grandfather or great-uncle, or something (this was 35 years ago)...but part of the same family, anyway. Not exactly like "Smith."

Not as famous as occupying the lab down the hall from Phil Smith at Bell Labs. As I was coming in to work there as a work-study student intern, he was leaving to retire. Same lab, though.

Agreed, cage nuts are the superior item, but I find the variety of sizes to be difficult at times.

I usually wind up with 100 of all the sizes except the one that matches the bolts that I'm holding in one hand while I'm trying to balance the server on the other shoulder and align the ##### holes!

Why am I holding the wrong bolts? Because I did the size test on the one of the eight cage nuts in the rack that didn't match the other seven!

On a bad day I just pull out the cage nuts and fasten the gear to the rack with twisted bits of cut-up coat hanger. Nobody says anything, but their eyes speak volumes. http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif

Anyone my age who doesn't remember Fahnestock clips was doing something besides radio.

I used lots of them to bulid crystal radios, regens, and even the first transistor oscillator I ever made. I still have a breadboard crystal set with Fahnestock clips on it somewhere.

Back when I was a whippersnapper, my older brother and I had this all-in-one electronics thingy. Had a bunch of Fahnstock clips on a yeller cardboard chassis you could reconfigger to be a regen radio, or a code practice oscillator, and a few other things. Had a single dual triode octal tube right in the middle. Forgot who made the things but they were pretty popular. Probably selling on E-bay for $4500 or so.

I had one of those, too. Forget it if was from Heath, or Eico, or Dyna, or Zenith...or somebody.

Anyway it used Fahnestock clips as I-O ports and DC connections for battery hookups and such, then used "springs" to make wire-to-wire and wire-to-component connections and using the supplied parts you could build a crystal radio, or an intercom, or a wireless AM broadcast transmitter, or a missile launcher. http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif

I worked my way up to missile launcher. I pushed the button, the light lit up and I heard a loud explosion from two counties over. I had no control over the launch, since I couldn't see the silo.

Meant to say, I'm 46 and I used Fahnestock clips as a teenager too. Crystal sets and all sort of other stuff.

[KC9JIQ]

Where I work they are called "U-clips". #Where the "legs" are to catch the thread of the bolts, the ones we have have actual threads stamped/taped into it, so it is more of a integrated nut/u-clip.

I had a kit like that but it came from Olson electronics. Mine had a plastic chassis and besides some resistors, capacitors, and diodes had two CK722 transistors. You couldn't make a regen with it but you could build an audio amp for the crystal set. Probably also worth a small fortune on Epay.. http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif

Thanks for all the info about those crummy little clips I got a jar of at some hamfest. I, too, am of a 'certain age' and have had a love affair with Fahnestock clips my whole life (just for the record, I like girls too) and have seen ones that had the name on them with a patent date around 1904 or something.

Fahnestock Clips....used a lot on American Flyer electric trains; also were the hook-up method in the 50's "no solder" Air Champ radios. #I had 2 crystal sets and the two-tube radio.

But a pic of one of those will always immediately evoke the memories of my beloved American Flyer Trains!
