Humbucker Bobbin Screws

Description

These humbucker slug screws are designed for use in standard humbucker pickups and serve as the threaded pole pieces on the adjustable coil.

Manufactured from steel, slug screws transfer the magnetic field from the bar magnet to the strings while allowing precise height adjustment for string-to-string balance. Consistent screw dimensions and threading are critical for smooth adjustment, stable mounting, and predictable pickup performance.

These screws are suitable for new pickup builds, rewinds, repairs, and restorations, and are commonly used in both vintage-style and modern humbucker designs.
