The Makita 136240-5 Anvil A Assembly XWT15 supports proper socket connection and torque transfer in compatible impact wrenches. This replacement anvil connects the socket to the tool’s drive mechanism, transferring rotational force to the attached socket during fastening or removal tasks. Proper anvil function helps maintain secure socket engagement and consistent tool operation. It is suitable for replacing a worn, damaged, or faulty anvil assembly during maintenance or repair. Installing a correctly fitted replacement can help restore torque transfer, reduce socket-related issues, and support normal impact wrench performance during regular use.
