The original Grover® Sta-Tite™ machine heads are now available for ukuleles, with an 18:1 gear ratio for precise tuning, still with the classic styling and butter bean button of the original Grover® Sta-Tite™ machine heads.

To establish stable and accurate tuning, the precision engineered open worm drive has been designed so it’s virtually impossible for the shaft to spin backwards.

The U99-18N comes with a .827″ (21mm) long post. Heavily nickel plated.

Set of four includes bushings and wood screws.

For detailed specifications and/or fitting guides please locate this item on the Grover website where they offer more detailed information.
