AN ABSOLUTE MUST
Locknuts at a dollar a piece. An absolute must have in every fingerboarder's spare kit. There's no denying these pieces can easily be lost. Once they bounce out of sight, it's very likely you'll never see it again. Unless, of course, you have spares. They won't break the bank and you'll definitely have piece of mind when disassembling and reassembling your set up.
You can never have too many locknuts...NEVER!!!
