This is a complete set of four heavy duty 1 2/4" long Neck screws and four 9/16" diameter countersunk screw mounting bushings.
You use these when your guitar has an offset neck screw pattern. These are exact replacements for Many Ibanez, ESP, Fernandes and Washburn guitars and basses.
As with all of my items, this is a brand new, factory fresh unit. I DO NOT disassemble guitars, pawn off used parts as new, or sell parts from the big catalog distributors.
