  • Whatchamacallit ? (..fasteners)

    What's the name for those push-on type nuts that are just a thin piece of sheet metal slightly dished in the center, with two (usually) little opposing spring segments that grip the non-threaded stud ...kinda like a chinese fingerpull?

    You're so close--they're called push nuts. See: http://www.mcmaster.com/ and enter "push nut" in the Find box.

      Hi lynn. As you said, they are called push nuts, or sometimes, push on retainers. MSC and others sell them in quantity

        They are Tinnerman Nuts.

        The type Lynnl is referring to are "spring nuts". "Push nuts" are round with six teeth.

          Well, I'm sure I'd heard the term 'push nut', but just assumed the user was like me, and was just using that term 'cause he didn't know what else to call 'em.

            Tinnerman nuts loop over the edge of a piece of sheetmetal to hold itself in place.

              Tinnerman makes many types of such nuts and it has become a generic term for them.

              The one you are referring to Joel is a clip nut or speed nut.

                The part you desire is called a [email protected]%&#**nut by anyone trying to remove it without a grinder!

                  These are push nuts, Tinnerman makes them, but a "tinnerman nut" is something different.

                    wierdscience:
                    You can remove them by inserting a small prybar - I mean blade style screwdriver (non-hollow gound, of course) - under the teeth and pry up. The teeth will either snap off, or if done right open enough to remove push nut. As easy as e^-(pi*i). (-1 if you care)

                      The weird one has the correct name in my book. I use the full name which is much longer. But he has the common pet name for them. Since clerks in hard ware stores are so dumb (mostly) I learn whatthey call things and ask for the thing by clerk name. So a roll pin, split pin and metal dowell are same thing in same store if you can get some one to open the show case and remove it. Most clerks understand if you show them a sample EXACTLY like you want- always buy morethan you need becasue it saves talking ot a gum chewing clerk.
