F77 Power Driver Screwdriver Sets

Our F77 Power Driver Screwdrivers are for repairmen who love solid, fixed-blade screwdrivers that fit correctly. These repairmen take pride in their tools and workmanship. This design is available with blades that fit nearly every woodwind or brasswind screw. This allows for excellent control which helps to eliminate slippage, scratching or injury.

We started with the tip of the blade, the part that has to fit the pivot screw and rod end slots perfectly. The tip is the most important part of the repairman’s screwdriver. The blade tip area is precision ground to a semi-hollow shape to give them maximum strength. The improved design parallel section is then ground to fit the slot of the screw or rod. This is what keeps you from “buggering” up the slot and post hole; a blade tip that evenly distributes the turning torque applied at the handle to the full width and depth of the pivot screw or rod end slot.

Each of these screwdrivers comes with a black anodized finish on a finely knurled aluminum alloy handle for a firmer feel, which provides you with more torque for easier turning of stubborn screws and rods. All of the tops are hex shaped, so they will not roll off your bench and they are color coded for quick reference.

Six of the most commonly used rod and screw sizes were chosen for this collection of fine drivers. Two of them come in two lengths. They are available individually or in a complete set of 8.
