    Click bait I know. I need to see what the back panel cabinet screws from the late 60s and the late 70s looked like, preferably with the trim washer.

    Any other interesting Marshall screws would be helpful as well, head cab, head back panel, chassis bolts etc.

    I have 3 cabs and I’m not sure if any of them are right.

    Thank you.

    If you post pictures of the screws, together with a description of the cab, we can provide a veiw. It's easier than asking people to disassemble cabs and take photos.

    I've disassembled my '69 1960A some time ago for a touch up; needless to say it didn't happen yet :D

    Since then, I've lost track which screw is used for what, maybe you guys can chime in.

    The middle ones with washers are for speaker mounting (left) and I'm 99% the middle right one is for back panel. I'm not sure about the ones on far right and left, maybe they are not from that cab at all...

    Why not just show us yours and we will tell you if original or not? Any non-original screws should be pretty obvious. The back panel screws should be the same as the ones in the baffle, but a little shorter.

    They used the raised head pozi in the 60's, flat head pozi in the 70's. Transition was about mid 1970. They used various length screws depending on where they were used and the size of the cab.

    Well I know the middle ones with the star washers are Cheeseheads and are for mounting the speaker frames. Can’t help on the left.

    I’m not so much trying to authenticate mine as use yours as a guide for replacement. I have at least 1 1/2 cabs with wrong screws.

    Cabinets sound better when they’re totally screwed!

    Front left are the 'pan head' screws for the metal handles. Far right look like baffle screws. The screws for your back panel look a bit too new to be original, but they do have the raised heads and a bit of patina, so maybe.

    Obviously I picked out the best of the bunch for the photoshoot :D

    These cup washers seem about right, what do you think?

    Yes I think those are the ones I normally buy. Size 8.

    Stainless steel is the best modern screw type to go for. Avoid the zinc plated ones - they do not look right on vintage gear.

    Thank you gentlemen. I got it, countersunk oval heads.

    When did Marshall end use of these? Or did they?

    I have a 1979 slant cab that’s all countersunk flat head Phillips and my jcm800 era and modern 2061cx are flat too.

    I ordered some #8s from BoltBase and they seemed smaller in diameter than they should be. Should the 4X12 screws be #8, 1.75 inch and back panel be #6, 1.25 pre 1970?

    I've got #8 x 1.75" screws listed in my notes for the baffle & back panels...

    Back panel screws are #6 for sure. Just don't know exactly the length.

    Is that #8 for the 4x12 back and #6 for the heads backpanel?

    size 8 in the amp heads too to my knowledge. I sold loads of them earlier this year and no-one has complained they were too big. If you buy new then the modern size 8 is a little bit thinner than the old ones.

    2" length, size 8 = 4x12 baffle screws
    1.75" length, size 8 = 4x12 back panels
    1.5" length, size 8 = smaller cab back panels
    1.25" length, size 8 = amplifier back panels (and the wooden strip on 67 and 68 cabs)
    1" length, size 6 = handles and feet.

    1" 2BA cheese head = 4x12
    0.75" 2BA cheese heads = smaller cabs
    0.75" 2BA chrome pan heads = metal handles

    0.75", size 6, slotted black dome head = metal castor cups (and sometimes the plastic "egg" feet)

    raised head pozi until mid 1970, flat head pozi from then onwards, apart from a stint in 74 when they used flat heads instead of pozis.

    and don't say I never share my info ;)
