The Allparts Plastic Bass Tuner Washers provide a practical solution for maintaining a secure fit between your bass tuners and headstock. Designed to reduce metal-to-wood contact and protect the finish around tuning peg holes, these washers help prevent wear and minimize unwanted vibration. 

This set includes eight durable plastic washers, making it suitable for most four- or five-string basses with 2x2 or 4-in-line tuner configurations. Whether you're assembling a new instrument or replacing worn components, these washers offer a subtle but essential upgrade for maintaining the longevity and stability of your bass hardware.
