    Default what size flathead screw for a 1920 F2 pickguard clamp

    Friends, Can anyone point me to what and where for the correct period replacement screw (I don't know if 'flathead is correct - probably slot head is better term since the screw is rounded)??Click image for larger version.

    That is a "round head wood screw" with a "slotted head." I believe the size is #3 x 3/16".

    The old Gibson screws were nickel plated. An exact replacement might be hard to find; nickel plated screws are no longer in common use. A similar screw in brass would work, though. If you can't find 3/16", 1/4" will work. Nobody will know the difference unless they take the clamp off.

    Check a very old-fashioned hardware store if you can find one. There's a chance that Ace Hardware might have one in their bins, but I wouldn't count on it.

    You will need a thread diameter of ~.100", +/- perhaps .003".
    .090" would be too small, .110" too large.

    You could call Stew-mac and ask them what the thread diameter of their #3340 screw is. It might be too small, but it's worth a phone call.

    I have found Bolt Depot to be very useful for certain odd screws that are hard to find. Unfortunately, 1/4" is what they offer here. They have #2 also This is one of the few places I've found that has many #3 screws available. Unfortunately only in brass

    FWIW, this post is worth about a day's worth of searching the internet effort on these two items. My initial search was for the correct screw for Loar pickguards. Bolt Depot has most anything for an old Gibson

    Would that be this product (Silverplater)? If so that makes my day. That would resolve some real issues for me.

    No, same company, but you have to look a bit harder on their site to find the silversmith. It contains a small dose of sodium cyanide that makes it work much better. Sometimes you have to call them to get it. Sometime you have to claim to be with a company, sometimes they don't ask

    SILVERSMITH contains cyanide and can only be sold to businesses.
    OK, that might be why it isn't on the website.

    I feel like I owe you an apology. I had read the product description only up to "SILVERSMITH contains cyanide" and, having verified that it was the correct product, rushed back here to share the information without reading the 7 most important words on the page - "and can only be sold to businesses"

    No apology needed, you found the product and that's what I needed. Thanks.

    To further clarify, I have not had much trouble obtaining it. I just say I'm The F5 Journal and I make mandolin and guitar parts. It contains 1.5% Sodium Cyanide. The formula still works well, but not quite as good as it did in the 90's.

    You can take a small glass custard type bowl and usually do 10-12 nuts, or screws, washers or rods (think pickguards) and just swirl them around in say 1/8" of the solution and then dispose of and rinse with water
