Lead screw driver

A lead screw driver system comprising:

• drive head means for engaging and driving a complementary driver head portion of a threaded fastener;
• manipulator means for selectively positioning said drive head means and a fastener engaged therewith for alignment of the same for driving said fastener into a given location in a workpiece;
• motor means for rotating said drive head;
• mounting means for operatively coupling said motor means to said drive head means;
• and brake means operatively coupled to the manipulator means;
• said brake means being selectively actuatable for holding said manipulator means against movement and selectively releasable for permitting movement of said manipulator means;
• and further including lead screw means operatively coupled with said drive head means for advancing the same at a given rate corresponding to the thread pitch of the fastener to be driven thereby so as to minimize stresses upon the material of the workpiece during the driving of said fastener.
