Look's like Harbor Freight Tool Catalog. Good deals on cheaper tools, and a tool like these bars will never be used at anything near their breaking point for this kind of work so you will probably never need the quality of Armstrong, SK, Snap-On or the like. Use your money to buy high quality sockets and hex key sockets where fit , finish and quality make a difference when in contact with the fasteners. Use your hard earned money to buy the quality torque wrench you'll need to have.
