These are the three steel screws that clamp the sustain block to the base plate on a Floyd Rose SpeedLoader tremolo. If one has stripped, cross-threaded, or gone missing, the block cannot seat correctly against the plate — the bridge rocks or the block rattles loose under string tension. This set of three is the direct replacement for that fastener.

Before ordering, confirm these screws are going into a SpeedLoader base plate. The SpeedLoader uses a different mounting pattern from the Original Floyd Rose and its licensed derivatives. If you bolt SpeedLoader screws into the wrong plate, they will not draw the block up flush. The block length also has to clear your body cavity — too long and it contacts the cavity floor before completing a dive, too short and the springs sit at the wrong angle — but that is a block selection question, not a screw question. These screws fit only the SpeedLoader plate.

Material is steel. No measurement or thread specification is published by Floyd Rose for this part, so if you have a stripped screw in hand, bring it to a fastener supplier and match the thread before assuming this set will drop straight in — thread pitch on tremolo hardware varies across production runs.

If you are not certain this is the right fastener for your guitar, send us the make, model and year and we will check against what we have on the shelf.
