Forged from heat-treated cold-forged steel with a black manganese phosphate surface finish, this ultra-lightweight 4 oz (0.25 lb) impact-rated attachment measures 4.36 inches high by 0.77 inches wide and incorporates internal spring-loaded coaxial socket sleeves across 9 mm, 11 mm, 13 mm, and 14 mm hex sizes. Engineered to withstand high rotational torque and impact driver vibration, this drive system enables industrial technicians, commercial electricians, and equipment mechanics to depress internal socket walls directly over bolt heads for immediate hands-free size switching without detaching the assembly from extended threaded studs or cramped electrical enclosures.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eBest Used For:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetric Industrial \u0026amp;
