Constructed from high-strength steel, the OTC 1925 resists rounding under high torque and provides the 5-inch depth needed to reach recessed locknuts on many passenger and light-truck spindles. It is specifically intended for hand tools with a 3\/4\" square drive; using impact tools will void the socket.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this socket prevent rounding and slipping on locknuts?\u003c\/h3\u003e\n\u003cp\u003eThe OTC 1925 uses an 8-point geometry and precision-formed opening to maximize contact with the flats of a locknut, distributing torque across more surface area. The heat-treated steel construction preserves the socket profile under load so it maintains fit and reduces fastener damage over time.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e8-point head for solid engagement with flat-to-flat locknuts\u003c\/li\u003e\n  \u003cli\u003eHigh-strength steel resists deformation under high torque\u003c\/li\u003e\n  \u003cli\u003ePrecision machining ensures consistent fit on 3-3\/4\" flats\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat drive size and tool type should I use with this socket?\u003c\/h3\u003e\n\u003cp\u003eThis socket is designed for manual 3\/4\" square-drive tools only.
