This is a set (6 in line) of genuine Grover Mini Roto-Grip Locking Rotomatic(R) tuners in nickel, part number 505FVN, new and blister packed. This set is specifically made to retro-fit Fender electric guitars. The posts are the correct diameter and depth, while the spacing and position of the mounting screws on the housings are correct for easy drop-in retro-fitting. These are the newest addition to the Grover line of tuners. These utilize a thumb screw mechanism on the back side which locks the string in place. You insert the string through the post hole, wrap around once, then lock by tightening the thumb screw. This is a perfect replacement for standard machine heads. The gear ratio is their famous 18:1 Rotomatic(R) design with precision cut worm and gear for perfect meshing, eliminating backlash and slippage while making tuning more precise. Gearbox is permanently lubricated. Post hole size is 21/64"(.328). All necessary hardware and screws are included. Upgrade that Strat or Tele guitar easily with some new hardware today! No modifications necessary. Take off the old ones, put in the new. These come with a lifetime factory guarantee. Return to Grover for a free repair or replacement. |
