Abstract
A controlled force drive element, for use with a rotational power tool, including a spring loaded drive line that exerts a preselected force on a fastener engaged by a drive head as the drive head rotates and advances the fastener. The drive element includes a primary drive body including a chuck connector to join with a chuck of a tool, an optional secondary drive body, a tool bit and a biasing element. The secondary body and tool bit are reciprocally joined with the primary drive body. A biasing element is joined with the primary drive body and/or the tool bit, and configured to compress under a force as the drive head engages the fastener to allow the tool bit and the drive head to retract toward the primary drive body. The biasing element is disposed along the spring loaded drive line between the chuck connector and the drive head.
