Floyd Rose Hex Screws




When assembling a Floyd Rose tremolo or simply replacing some parts, it's good to understand a little bit about the metric screws it requires. Floyd Rose sells its own replacement screws in black oxide steel and stainless steel, but they're not cheap and they're not always in stock. There are plenty of aftermarket screws available and one can even go after multiple-color, anodized titanium screws. The table below describes the metric screw sizes and characteristics one would need to be able to source these from an online screws/bolts dealer. Even the hex nuts for the Floyd Rose Non Fine Tuner (NFT)...
