Abstract
Apparatus for engaging and turning spanner type threaded members has an upper jaw member extending from a handle and terminating in a 90° arcuate radiused portion. A cylindrical lug extends radially at the end of the radiused portion for engaging the threaded member, and a clamping jaw member is pivotally connected to the handle so as to be diametrically opposed to the lug. The clamping jaw member is forced toward the upper jaw member to provide a clamping force on the threaded member and force the cylindrical lug into positive engagement with the threaded member.
