Milwaukee 1/2 in. Square Anvil Assembly with Detent Pin
Model Number: 42-06-0047
The Milwaukee 42-06-0047 is a genuine OEM 1/2 in. Square Anvil Assembly with Detent Pin for compatible Milwaukee 1/2 in. impact wrenches — a complete output anvil assembly including the anvil body and the spring-loaded detent pin retention system that secures sockets on the anvil's square drive during impact wrench operation. The anvil is the 1/2 in. square drive output component of the impact wrench that transmits the tool's rotational and impact torque to the socket — the anvil body must withstand the extremely high peak torque loads generated by the impact mechanism's hammer-anvil impact cycles without deformation, cracking, or fatigue failure at the critical anvil-hammer interface or the square drive socket seating geometry. The detent pin provides the ball detent or pin detent system that retains the socket on the anvil during operation, preventing sockets from backing off under the vibration and reversing loads of impact wrench use.
When an impact wrench anvil assembly wears, develops cracking from metal fatigue at high torque operating cycles, loses the detent pin retention force that allows sockets to slip during fastening, or sustains physical damage from socket-related impacts, the anvil assembly must be replaced to restore the tool's rated torque transmission capability and safe socket retention. Using a genuine Milwaukee OEM anvil assembly ensures the correct dimensional specifications for impact hammer engagement geometry, socket seating fit, and detent retention force for the specific 1/2 in. impact wrench model — aftermarket anvils with incorrect hammer engagement geometry produce reduced torque output and accelerated anvil wear. Always verify your specific Milwaukee impact wrench model number and serial number at milwaukeetool.com before ordering replacement anvil assemblies.
