Darn those vintage Fender speaker mounting screws!

    I can´t believe experienced Techs such as Randall and nevetslab weren´t aware of this, it has been THE Fender speaker mounting method for decades and you have each met at least dozens of Fender amps.
    I´m bewildered.

    In fact, there´s two versions: the "good" one involving dual threads and the cheesier half thread half winged nail so it does not rotate:





    notice the ad copy:


    Original Fender speaker mounting stud/nut set.

    These speaker mounting studs were used on countless amps of the 50’s, 60’s 70’s and beyond. The reverse thread section screws into the baffle wood and the machine screw section holds the speaker in place using the included keps nuts.

    Used on early ’50s and ’60s vintage amplifiers
    Fits most vintage and modern amplifiers
    1” of 8/32” machine head thread
    ¼” of reverse wood thread
    1-½” overall length
    8-32 keps nuts included
    Set of 12
    these are the cheapies:

      Hmmmm... I don't know if I'd call the 2nd variety "cheapies," as they do seem that they might not strip out their mounting as easily like the way I discovered them...

      Either way, I think they were/are an elegant and creative solution to a problem that we now probably take for granted...

        Living in Argentina I had to improvise, as always.

        I use regular machine screws, flush mount head, of course, drill a slightly too small hole in wood so it has to force thread its way in, of course proper thread, not reverse, and also not coarse "wood" thread , and when head is one wood thickness away I add a dab of epoxy to thread, then drive it home until head is flush ... works like a charm.

          Well, that shows you how many Fender baffles I've taken apart, removed the grill cloth from, extracted these odd-ball fasteners. I never gave it a second thought, apart from being careful not to puncture the cone of a replacement speaker getting it onto all eight of the spikes, and trying NOT to impale my hand when reaching up into the upper cavity by braille to tighten loose mtg nuts.

          Always continual education here!

            JM: I'm actually surprised how few times I've ever had to deal with these screws. If you don't do a lot of cabinet or speaker work, I guess it's possible to never have to deal with them.

            I don't like the idea of those winged screws. You either have to pound them in, or tighten the speaker enough to risk warping it. Or it just doesn't seat all the way.

            Here's a fun one. What's wrong with this picture?

              Coarse threads are right-handed. Not sure about the machine threads. Mirror image?

                Here's a picture of the same screws (with the lower tooth count lock washer) available from TAD. It looks to me like both threads are right handed. If they're mirror image then both threads are left handed. I wonder how a mistake like that gets made

                        Hopefully not for the same reason you don't shake someone's left hand.

                          Well, I certainly knew of these screws, I've had bag of them waiting in my shop for over a year for the cab guy to build me my cab. It just never occured to me they were reverse. I drilled my holes about the same size as the machine stud, so instead of just pushing into the hole, I drove them in with a driver. When I came to the wood screw threads, that's when I got very puzzled for a bit.

                            The hand you shake with (always seems to be the right) has different reasons in different cultures. In India, yeah, you don't shake lefty. They take it pretty seriously too and it's considered a very offensive insult to offer someone your left hand.

                              Pretty much the same all over the mid east, the "sub continent" and north Africa besides. If you really want to make a - bad - impression, pull off your shoe & smack 'em with it. Or just heave your shoes at 'em if beyond swatting distance.



                              George was pretty good at ducking! Perhaps the shoe toss was a frat party activity he was good at.
