Purpose-built for tight, stubborn fasteners: Designed for automotive workshops, motorcycle maintenance, industrial equipment service and home garage projects where bolts and nuts are hard to reach or seized in cramped spaces. Professional 9-piece end socket extension bar set: Nine precision-made extension bars and end sockets give you the reach and variety needed for many mechanical tasks without having to remove surrounding parts. Durable alloy steel construction: Heat-treated alloy steel meets industry specifications for strength and wear resistance, so the tools withstand repeated high-torque use and deliver long service life. Secure, high-torque performance: The solid-steel construction and precise fit provide superior torque transfer with reduced flex, helping prevent rounding of fasteners and minimizing tool wear. Swivel head with hex drive for angled access: The swivel-head design plus hexagonal drive allows angled operation to reach into confined engine bays, behind brackets, and into other tight work areas where straight tools cannot reach. Non-slip handling under load: Engineered surfaces and a solid connection to sockets reduce slipping during heavy-torque applications, improving safety and control. Compatibility and function Works with standard hex-drive sockets and attachments to extend reach and provide leverage for a wide range of mechanical jobs. Purpose: extension, angled access, and improved torque delivery for maintenance and repair tasks. Typical applications Automotive workshops: Reach bolts deep in engine bays, behind suspension components, or around exhaust manifolds without dismantling nearby parts. Motorcycle maintenance: Access fasteners under fairings, around the engine, or in narrow frame sections where space is limited. Industrial equipment maintenance and home garage projects: Service conveyor guards, pump housings, control cabinets and other machinery with recessed or obstructed fasteners. Why choose this set Ready for professional use: Nine-piece set covers many situations so you have the right extension at hand. Built to last: Heat-treated alloy steel and precise manufacturing deliver reliable torque performance and long wear life. Improved efficiency: Angled swivel head and secure hex drive reduce time spent fighting hard-to-reach fasteners and lower the risk of damage to parts. Includes Professional 9-piece end socket extension bar set made from heat-treated alloy steel with swivel-head hex drive for angled access and superior torque transfer.
