Extended long shaft design easily accesses deep, recessed, hard-to-reach bolt positions that standard short sockets cannot reach, ideal for narrow gaps and deep mounting spaces in machinery and furniture assembly. Each hex socket head features a powerful internal magnet that firmly holds nuts and bolts during high-speed drilling, effectively preventing fasteners from dropping off and boosting work efficiency. Made of high-strength hardened steel with anti-rust matte finish, resistant to wear, impact and deformation under heavy torque; stable performance for long-term frequent industrial and household repair work. Standard 1/4" hex straight shank fits most electric drills, impact drivers, cordless screwdrivers and air tools, widely compatible with mainstream power drill equipment for all repair scenarios. This set covers common metric sizes from 6mm to 19, Manufacturer: Ruxyoie88
