Golden Age Neck Mounting Ferrules, Black, package of 12

For bolting a neck onto a contoured solidbody when a flat neck attachment plate is impractical.5/8"-diameter counterbored holes required. Supplied in packages of 12.Mounting screws sold separately. We recommend using a Forstner Bit, or brad-point drill bit to recess these neck bolt ferrules to 3/16" standard depth (this may vary according to instrument design). If you're drilling the holes before applying finish, use a 5/8" diameter bit—it'll make a slightly oversized hole to allow for finish thickness in the recess. Use a 15mm bit if you plan to fit the ferrule with no finish in the recess.
