Some original factory installations used incorrect screws for the top plate and bottom plate. Our recommended screws (located in "Add to Cart") are sized correctly.

In addition, not all dovetails are created with exact same angles. If too loose, add and glue shims for a snug fit. If too tight, try to spread steel but still maintain a snug fit.
It is the bottom plate and screws which provide the strength needed to the legs. Many older 4 leg bases have broken screws which originally fastened the hub bottom plate. It is important to remove and replace those screws. Drill a 1 1/4" or preferably larger hole, and glue in an hardwood Hard Maple dowel. Purchase the Maple dowel first, then the drill bit. When dry, drill a correct size pilot screwhole to fasten the bottom plate.

What is a Dovetail?
This is a photo of a Dovetail
The leg end slides into the provided space on a hub to keep it from falling off. Dovetails are machined at precise angles to hold tightly thus providing strength. The entire user and chair weight is carried by the dovetails and bottom plate.
