Abstract

See full text

A tool may loosen seized bolts by sending shock waves into the bolt shank and thread areas via axial blows with a pneumatic hammer on the center of the bolt head prior to removal. The tool may allow impacts to be centered on the bolt head without damaging the bolt head or without worry of the bit jumping off the bolt. The tool may be comprised of a separate driver and one or more sockets.
