It fits over the large locknuts on spindles and axle ends to tighten or loosen them during wheel bearing maintenance. The thin-wall, precision opening grips the nut securely without rounding it off, and it’s meant for manual use with a torque wrench or breaker bar—never with impact tools. You’d replace your existing socket when it wears, rounds out, or you need the correct size for a routine brake and bearing job.
