Forged from heat-treated cold-forged steel with a black manganese phosphate protective surface finish, this 6.8 oz (0.43 lb) impact-rated assembly measures 7.1 inches high by 0.96 inches wide and incorporates internal spring-loaded coaxial socket sleeves across 1\/2-inch, 9\/16-inch, 5\/8-inch, and 11\/16-inch hex sizes. Engineered to endure high rotational torque and severe vibration from power impact drivers, this system allows commercial electricians, steel erectors, and HVAC contractors to compress internal socket walls directly over bolt heads for immediate hands-free size switching without removing the tool from long threaded studs or tight electrical enclosures.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eBest Used For:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eImperial Structural \u0026amp;
