    Which is the correct way to bolt a 550b to workbench

    I use a wash under the bolt head if for no other reason than to keep from marring the press. Kind of silly I know but the points of the head can dig in, and the washer helps distribute the load. I will be mounting mine today and will use washers on both the head end and the nut end.

    I would put a washer under the head of the bolt....Pretty much a rule of thumb with fasteners to get proper torque and protect the surface as well. It provides more surface area under the fastener. I also place one under the nut if you are using one.

    What are (plain) washers for?

    They spread the load of the bolt's head over a wider area. Useful if you are bolting a piece of wood or soft or thin metal.

    They prevent scratching of the paint of the item being bolted.

    They allow spacing the bolt's head higher off the item being bolted. This may help with access to the bolt head.

    I suspect they don't specify because it doesn't matter. If you really want to know for sure, Dillon's customer service is said to be the best.

    Personally, I would use the washer. Cost is a few cents. Because there is (appears to be) a raised area at the bolt hole, cleaning under the edge of the washer might be a problem, but if you use a washer the same size as that raised area's diameter, that should be cured.

    Congratulations on a fine press.

    With the bolt head against the metal base of the press there's no need for washers, unless you just like the look of them
    At the nut end is where a washer needs to be. If you're bolting to a wood bench, maybe even a big heavy duty fender washer and a split or hardened lock.
    Mine is bolted to a 1/2 inch plate, so I just used a split lock underneath. Did use grade 5 bolts, but mostly because I never keep any soft bolts around.

    Look in your manual on pg. 6 figure 2...no washer installed.

    But its your call.

    I mou8nted my Dillon 550 on a varnished 3/4 inch piece of solid core plywood which is fastened to the bench with two C clamps.

    That's the way I did originally (no washer). That must have been where I saw it. However, I removed my press off the bench today to put a new table top on the bench and noticed that the paint was scratched off the press from contact with the bolt head, so I'm putting washers there when I re-install it.

    Wonder if Dillon can send me some touch up paint.

    No, Dillon's castings are powder coated.

    But an engine enamel called "Old Ford Engine Blue" is a close match. Duplicolor makes it I believe.
