    From the shop manual for my 1954 Matchless G3LS, instructions for torqueing the head bolts: "Tighten each in turn, bit by bit, until all are fully home."

    I loved the look of the 3G's, sort of like a one lung Harley XL. Speaking of which, the HD manual was something like tighten to 14 ft lbs, then to 40ft lbs, then 1/8 turn. You were supposed to scribe the head fastener and observe its indexing... :)

    I think they got that scheme from the Morris Minor.....

    The reason is that you can visually tell if a screw has moved.

    Gently rotate your tool until slight friction is felt and stop and then with just a hint of torque to complete.:)

    Screw those screws! Just use a couple self-adhering strips of Velcro.

    I think on the Warmoth forum, there was a guy who used locating pins with corresponding holes in the body, and... magnets... to hold the PG on

    no, I think his friend is likely to be the type while camping to ask him to go to the car and get a left handed smoke shifter.

    for vintage guitars, build a number block with holes in it - as to put the same same screws in the same holes, 1 just because the tops will be worn differently, and two - because it shows your customer that you really care for his or her vintage guitar.

    Put them all in a turn or 2.
    Tighten them in any order.
    Just before they strip....STOP!

    I had a feeling that in door hinges at least the slot should be vertical so that dust doesn’t collect in it as it would if it were horizontal, but I can hear my late dad and grandad groaning at such a daft idea. I like your reason much better aerhed.

    I am not even sure how you would measure torque using a small philips head or slot screw driver. Does that type of screw driver exist? If it does and StewMac gets wind of this thread expect an overpriced version of it soon.

    https://www.amazon.com/dp/B07C3HW56N/?tag=tdpri-20

    So, I guess that they do exist. StewMac for $180 maybe?

    If the pickguard is dimpling around the screw, you went too far. Pickguard screws shouldn't look as if they're at the bottom of a crater. Start anywhere, then the second one is the one farthest from the first one. The third one is the one farthest from the second one that isn't the first one. Rinse and repeat. It's not rocket surgery. Or... IS it!?

    Trust me. If you can think of it, it already exists.

    Someone stole my glow-in-the-dark horseshoes idea. Even put a patent on it. Bastards.:p

    Just tighten the pickguard screws down until they seat in the countersink of the plastic/bakelite.

    If the screw hole seems stripped. Break off a toothpick in the hole with a dab of Elmer's glue and reinsert the screw. Let that set overnight and give it a slight twist in the morning.

    I've never seen a pickguard fall off anyone's guitar.

    OP here.
    Well, this turned out to be a complete sham, a farce.
    My lead player, a ruthless practical joker, sent me the original question, in a text message, preceded by "I have a question for your TDPRI folks....."

    So I posted it.
    I was skeptical, but this guy is known in the South Jersey region as a Telecaster Master. One of the best country players around. Plays a custom G Bender. Does his own setups and stuff. I trust him to know what he's talking about when it comes to guitars.

    That's why in the original post I state "Is there such a thing?"

    Yesterday at practice he confessed. He had a good laugh at my expense. Ha Ha.

    Same as you measure torque for any other fastener: a screwdriver bit and a torque wrench or a torque-limiting screwdriver.

    Phillips screws were designed so the bit will cam (slip) out of the slot when the right torque was reached. That was a century ago, when tools to get the torque right were very expensive. These days, if you're manufacturing something where getting the right torque consistently is important, you use a torque-limiting driver

    Obviously my link showed how you can. I wonder how many manufacturers measure the torque of their pickguard screws?

    The bigger joke is that people here took it seriously.
