Swivel-head design with hex drive enables angled access to tight engine bays and cramped work areas Optimized for automotive workshops, motorcycle maintenance, industrial facility upkeep, and home garage projects where stubborn screws require reach in confined spaces Heat-treated alloy steel construction provides long-lasting durability and a secure, non-slip grip for high-torque applications 9-piece professional extension bar set with a ball head and steel construction delivers superior torque transmission and wear resistance for precise mechanical tasks Typical applications and scenarios - Automotive maintenance: reach and turn fasteners located in crowded engine compartments or other restricted spaces without removing components. - Motorcycle servicing: access bolts tucked under frames or around tight bodywork during routine maintenance. - Industrial and home projects: maintain or assemble equipment in narrow spaces where long reach and reliable torque transfer are essential.
