Forged from heat-treated cold-forged alloy steel with high-torque impact rating, this 2.72 oz (0.17 lb) ASME B107.2 compliant tool measures 4.2 inches long by 0.68 inches wide and houses internal spring-loaded coaxial socket sleeves across 1\/4-inch, 5\/16-inch, 3\/8-inch, and 7\/16-inch hex sizes. Engineered to absorb extreme rotational impact loads, this multi-size attachment allows electrical contractors, HVAC technicians, and sheet metal installers to compress internal socket walls against bolt heads for instant hands-free size transitions without detaching the socket from power impact drivers.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eBest Used For:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheet Metal \u0026amp;
