Solo Flat Washer

Solo Pro flat washers are replacement flat washers designed for guitar electronics. They are made to fit potentiometers (pots), output jacks, and endpin or flush-mount jacks. Each washer sits flat under the mounting nut. This spreads the clamping pressure and helps keep the nut and mounting surface secure.

Key Features:

• Replacement flat washers for guitar pots and jacks
• Several inner and outer diameter options to match common metric pot and jack mounting hardware
• Flat design spreads fastener load and helps protect the mounting surface
• Made in Japan

These washers are a simple, low-cost way to restore or complete the hardware on guitar controls and jacks. Choose the variant that matches your component's mounting thread.
