Getting the right hardware for a piece can be as difficult as building it. These knobs, machined from solid stainless steel, can be customized to complement any piece. The insert can be made of wood, tagua, Corian or any other material you can shape. Just cut a plug of the material to be used, glue it into the knob and then shape the knob using either a bolt or our special mandrel (available separately) to hold it in a hand drill, drill press or lathe. A quick coat of finish (poly tung oil works well) and you have a custom knob that is also tarnish-proofed.
With smooth rims, these knobs have outside diameters of 3/8", 1/2" and 5/8" and require 1/4", 3/8" and 1/2" plugs respectively.
Made in Canada, the knobs come with a 6-32 × 7/8" flat-head screw for through-hole mounting. For blind-hole mounting, brass insert nuts and set screws are available separately.
