For bolting a neck onto a contoured solidbody when a flat neck attachment plate is impractical.
5/8"-diameter counterbored holes required (using a precision Forstner bit is recommended). Supplied in packages of 12.
Neck Mounting Screws sold separately.
We recommend using a 5/8" diameter counterbore, Forstner, or brad-point drill bit to recess these neck bolt ferrules to 3/16" standard depth (this may vary according to instrument design). The suggested 5/8" diameter is slightly oversize 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.
