How to select the correct MILWAUKEE impact socket for a 43 mm fastener?

Ensure the drive size matches your impact wrench (3/4" for this socket) and the socket size matches the fastener head (43 mm). A 6-point socket like this MILWAUKEE model provides better grip on hex fasteners than 12-point designs, reducing the risk of rounding under high torque.
