Forged from heat-treated 4140 alloy steel, this 4.1 lb ASME B107.33M compliant set incorporates a 12-point socket geometry that eases alignment onto both metric hex heads and square fasteners. Engineered for power grid maintenance, utility construction, and industrial machinery assembly, the hands-free spring mechanism allows operators to depress the inner socket sleeve directly over bolt heads to instantly transition across eight core metric sizes (13mm, 17mm, 19mm, 24mm, 22mm, 30mm, 27mm, 32mm) without removing socket bodies from impact wrench anvils.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #004b87;\"\u003eBest Used For:\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElectric Utility Pole \u0026amp;
