Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets the standard for closed tuning machines, featuring a refined 1:18 gear ratio for velvety smooth, precise tuning control. Each component is CNC-machined to exact tolerances and permanently lubricated with Schaller specialty grease for completely maintenance-free operation and exceptional longevity.
Equipped with high-grade brass string posts engineered for maximum tuning stability, these machine heads eliminate backlash through a self-locking drive. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing stress on mounting components.
Designed with a precise two-pin spacing of 0.39 in (10 mm) center-to-center and an 0.31 in (8 mm) distance between pins and post center, the M6 Pin ensures solid anchoring and seamless replacement for older single-pin M6 installations sharing the same housing dimensions.
