Forged from heat-treated 4140 alloy steel, this 3.5 lb ASME B107.2 compliant socket set features a high-torque 6-point design optimized for driving structural hex bolts and square fasteners. Engineered for electrical contractors, power line technicians, and steel erectors, the hands-free spring-loaded socket mechanism lets workers depress inner socket walls directly over bolt heads to immediately transition across twelve core sizes (3\/8\", 1\/2\", 7\/16\", 5\/8\", 9\/16\", 3\/4\", 11\/16\", 7\/8\", 13\/16\", 1\", 15\/16\", 1-1\/8\") without detaching sockets from 1\/2-inch impact wrench drive anvils.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eBest Used For:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectric Utility Pole \u0026amp;
