Ken-Tool’s latest fastener socket driver set’s design, often referred to as a “Spiral Drive,” with the driver engaging into the four curved “wings” in the faster head, allows the driver head to have complete contact with the fastener’s recessed drive head.

These features allow for uniform torque delivery, combating tool slippage and “rounding out” of the fastener head and the drive tool.

The higher surface contact area also makes fastener removal easier, including improved removal of corroded or seized fasteners.

The Ken-Tool 30260 set includes a 3/8” driver and M0, M1, M2, M3 and M4 drive heads and a steel storage rail.
