It fits locknuts measured 4 inches across flats and is intended for manual 3\/4\" drive use only; impact-tool use will void the warranty. The OTC 1914 blends durable construction, accurate fit, and the depth required to reach recessed locknuts while keeping torque under control.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this socket prevent rounding on wheel bearing locknuts?\u003c\/h3\u003e\n\u003cp\u003eThe OTC 1914 uses a 6-point profile and high-strength steel to maximize contact area and resist deformation under torque.
