Keep your guitar in tune with Grover's replacement washers.
The Grover Replacement nylon washers or guitar tuning machines provide essential replacements for worn or damaged washers in your Grover machine heads. Designed for guitarists seeking to prolong the life of their tuning machines, these nylon washers fit most Grover models, including the 102, 103 and 109 series. You'll enjoy smooth, unimpeded tuning action as the washers reduce friction between the tuning post and mounting surface. Built to tight tolerances, the washers enable precise adjustment of string tension for accurate intonation.
