Adjustable Tool For Driving Multiple Fasteners

Proposed tool tightens or loosens several bolts, screws, nuts, or other threaded fasteners arranged in circle on compressor head, automotive wheel, pipe-end flange, or similar object. Combines some features of related mechanism described in, "Tool for Driving Many Fasteners Simultaneously" (MSC-22386). Unique feature of proposed mechanism; lateral positions of output shafts adjusted, by use of mechanism called "selector," to fit fastener patterns with larger or smaller bolt circles. Concept extended from circular pattern to rectangular pattern for application to automobile headers and intake manifolds.
