Document Type and Number:
Japanese Patent JPH0669673
Kind Code:
B2
Abstract:
A stud driver has threaded jaws with thread relief provided on a leading edge area of the jaws to reduce thread marking or deformation of the thread on the stud when the stud is driven under high torque conditions. The thread relief in the leading edge area of the jaws creates a shallower angle and increases contact area. If the stud driver is subjected to unusually high torques, the increased contact area prevents shearing of the thread on the stud.
